Golf IV / Jetta IV :: Car Is Showing Codes For O2 Sensors
Sep 29, 2015
This isnt my first vw but its my first vr6, its a 2000 gti glx, only showing codes for o2 sensors havent got a vag com yet only have a obd scanner. It idles fine and runs smooth until i get over quarter throttle then it starts hesitating like there isnt enough fuel or air...i know that the noob owner i bought it from cheaply put exhaust on it and i didnt see any o2 sensors but ive never known a car to not run correctly without them.

Throwing codes here.... been seeing the P1347 consistently with the P0011 and P1143 intermittent.
I have checked the resistance of the camshaft adjustment valve resistance and found them to both be around 9 Ohm (spec is 10-18 Ohm).
I checked the voltage to both camshaft position sensors and they are in spec at 4.9 Volts
I swapped the camshaft position sensors to see if the code would follow the sensor but it did not so it is directly related to the intake camshaft.
It is looking like there is a timing issue either related to the adjustment valves going or possibly some contamination preventing them from working properly. They are both out of spec in terms of resistance which is odd that they would both go at the same time but possible.
The oil inside the camshaft position sensors is no good I cleaned it all out when I swapped the sensors but no change. These will have to be replaced.
Car has 125k on it so it could be due for timing chains but I want to rule out anything else first.

My gf's son has an old 2000 Jetta 2.0 and when the check engine light came on and shifted poorly, it was diagnosed as a problem with the transmission input and/or output sensors. Where are they located exactly?
Both look pretty much the same, but here's a pic of one of them : [URL] ....

While I drove to and from the dog park yesterday - a total of 25 minutes - several alarming things happened to my 2007 Jetta (2.5L, 4 Dr, single owner = me). On the way there, a yellow icon popped up on the instrument display, and since I'd never seen it before, I looked it up in the manual after we parked and went into the park. It was the power steering icon - not low fluid, but your power steering may stop working, better get it checked. (!) Yellow is the warning, and red with noises is the serious problem level. But it also said sometimes that symbol shows up and then goes away. After 90 minutes in the park, I started the car and it wasn't there. And I didn't feel any problem with the steering. Then, after 3 minutes of very low speed driving, the radio display started to flicker, and the radio popped and then shut off by itself. Then the instrument display that shows the mileage, the tank mileage, the temperature and the time in red numbers started to fade, I noticed the A/C was blowing warm air, and three more icons showed up: the power steering one, the ABS brakes, and another one I didn't recognize. I kept driving because I was in traffic, and then after about 2 - 3 minutes, the A/C got cool, the radio came back on, and the icons went away. I haven't started the car yet today, but it drove all the way home last night with no weird episodes.I was in an accident in June that required both drivers side doors to be replaced and a lot of cosmetic work on the back bumper, but no impact to the engine area or front of the car. Any thoughts on what's causing this? I have a long freeway commute and I am worried about driving with things just cutting out like that.

Okay I have a 2000 Jetta GLS VR6. I had the engine replaced after i found out the block was cracked when replacing the heater core. ever since it was replaced the car runs great but it keeps throwing these 4 codes.
p1424 secondary air injection system bank 1 leak detected -intermittent
p0411 secondary air injection system incorrect flow detected
p1603 internal control module failed self test -intermittent
p0134 02 sensor bank 1 sensor no1 no activity -intermittent
The thing that is bugging me is that the sai pump is still running. On cold start it literally sounds like a Dyson vacuum. What i should try.

My old pump wasnt building pressure so i put a new filter on and i switched wit a used one from an old car i had.key on engine off Pressure goes to 45 then instantly starts droppin? Once i turn key an do again same thing... Car is starting tho. fuel Pressure around 38 while idling. I pulled fuel rail up and looked for leakin injectors.. There was none yet pressure still bled down kinda quick. I also have my cat aloose to keep from messing it up any further. Only codes keep showing is po300 multiple misfires.

We've owned the 2009 LX570 (approx 101k miles) for about a month now. The vehicle has run fine, no issues. This morning it started very briefly (.25sec) then quit. Same thing over and over. I charged the battery, had it load tested and it all checks out fine. I cleared codes and rechecked it. No standard OBDII codes show, only the enhanced codes. Dash shows a CEL. We drove the vehicle yesterday a few times and all was fine...normal acceleration, started, etc. Then, this morning, it went down. I also pulled the MAF, cleaned it, reinstalled. Pulled the intake tube, cleaned the throttle body butterfly and corresponding area around the butterfly. It was slightly dirty but looked normal.
Here's what I have for codes:
P0300 Random Misfire Detected
P0011 Intake camshaft position timing - over - advanced (Bank 1)
P0012 Intake camshaft position timing - over - retarded (Bank 1)
P0014 Exhaust camshaft position timing - over - advanced (Bank 1)
P0015 Exhaust camshaft position timing - over - retarded (Bank 1)
P0016 Camshaft position - camshaft position correlation - Bank 1 Sensor A
P0017 Crankshaft position - camshaft position correlation - Bank 1 Sensor B
P0018 Crankshaft position - camshaft position correlation - Bank 2 Sensor A
P0019 Crankshaft position - camshaft position correlation - Bank 2 Sensor B
P0021 Intake camshaft position timing - over - advanced (Bank 2)
P0022 Intake camshaft position timing - over - retarded (Bank 2)
P0024 Exhaust camshaft position timing - over - advanced (Bank 2)
P0025 Exhaust camshaft position timing - over - retarded (Bank 2)
P0032 HO2S Heater Control Circuit High (Bank 1, Sensor 1)
P0052 HO2S Heater Control Circuit High (Bank 2, Sensor 1)
P0101 Mass or Volume Air Flow Circuit Range/Performance
I am uploading a short video to Photobucket, which perhaps illustrates what's happening better than I can describe. I will post it up once it clears on Photobucket. Cranking sounds normal and I can hear what sounds like the fuel pump activating as well. I know that low voltage on a CANBUS system can make weird things happen. However, since my battery checks out, I'm not sure on this one.

I have a 2002 Toyota Camry LE V6 with codes p1135 and p1155. Both sensors that are supposedly faulty have been replaced.
The new sensors are denso 234-9043 and 234-9047. I am confident that the second one was the right one replaced as both the new and the old had a little green marker(the location is near the firewall.) not 100% sure about the other one.
The sensors were brand new so I don't know what the problem is.

My truck is stumbling and losing engine power sporadically. When this is happening I can usually drive it if I am real easy on the gas and slowly build up speed but if I mash it the engine will eventually just die completely. It has had this problem off and on for several years and now it's back with a vengeance. It always seemed to happen after a heavy rain but now I'm not sure.
Last week I had a mechanic look at the codes and he cleared them saying that once it happened again the code(s) that showed up would be a good indicator of the actual problem. The codes that were there were for a couple O2 sensors, catalytic converter and loss of vacuum I think. It happened again and his shop was closed so I got it read and cleared somewhere else and it was P0131 bank 1 sensor 1 and since I knew that one had come up before I went ahead and replaced it myself.
The next day the CEL came back on without any noticeable engine trouble. That was yesterday, this morning it rained and the problem is back and I went to get the code read and it was the P0420. There was also C0281 stop lamp circuit something or other that was new.
My gas mileage has stayed pretty good this whole time, always 15+mpg. Just wondering if my catalytic converter probably needs replaced, if I should replace other O2 sensors, or if this all might indicate something else in the engine.

I changed both oxygen sensors yesterday on my 1997 Accord.
Check Engine Light was on and I was getting codes:
P0135 - O2 Sensor Heater Malfunction Bank 1 Sensor 1
P0141 - O2 Sensor Heater Malfunction Bank 1 Sensor 2
Also, after clearing the codes, if I started the vehicle the codes would come on instantly. So it wasn't some kind of flaky electrical issue, it was consistent.

I have a 1998 chevy 3500 2wd pickup with a 454 engine. The check engine light is on. I have had the codes read and they were for a MAF and MAP sensors. I have replaced both. The check engine light is still on saying that I have a bad MAF sensor. I replaced it again. The check engine light still is on. What else should I look at to fix this problem??

1997 2wd, 4.0 - As you can guess it runs pretty bad at idle. It has O2 heater circuit codes for all 3 sensors. I'm leaning towards the ECM because the 2 heater wires are both hot with the key on. I unplugged the computer and turned the key on and just one wire is hot. Looks like the ecm is supposed to ground the wire to turn the heater on, but it's going hot instead?

I have a 2001 1.8t beetle and doing some research to buy parts I came across two different engine codes. My trunk says I have a AWV engine but the cylinder head says AWM. This is really confusing as looking them up I get three entirely different options for this car.

I recently had an issue with a coolant leak. the Y shaped coolant line connection went bad located under the power steering reservoir. The car got hot and the coolant light came on i immediately turned the car off and saw coolant leaking out from this.
Now today I start my car it has a rough idle and dies once it dies it doesn't start again and the epic light comes on throwing the codes
17579 P1171 Throttle Actuation Potentiometer Sign.2 Range/Performance
17951 P1543 Throttle Actuation Potentiometer Signal too Low
16497 P0113 Intake Air Temp.Circ High Input

17953 P1545 Throttle Pos.Contr Malfunction
17976 P1568 Idle Speed Contr.Throttle Pos. mechanical Malfunction

My gf's 04 gti 1.8t 5spd is having idling issues. Here's the rundown, at idle it sits at 800 rpm but when given a rev it then becomes erratic and fluctuates between 500-1100 rpm. When throttled again lightly it returns to normal 800 rpm idle. The car will try to stall a little bit. Now for the codes and lights. The lights are the traction control light and the check engine light. The codes are p0102 (MAF) and p2181 (coolant system performance). I have recently had a misfire which I took care of with 4 new coil packs. I kept the 3 good ones I took out. I have to change the plugs still but don't think it's an issue. Has new clutch and sits at 148,852 miles.

Throwing 2 codes -
P0172: too rich
P1176: post cat 02 reached limit
Last time it turned on it had horrible air flow, it felt as though it was choking. definitely not a misfire. occasionally after spirited driving the engine would die after I came to a complete stop then worsened to cutting off when I put the clutch in at high rpms. also have a slight loss of power. I also recently added a 3" tbe and changed coil packs.

So my car has been dropping multiple codes after I scanned her and found all five: p0303, p1128, p0172, p1300, p0301. She is just a simple five speed AEG and has no mods other than a SRI. I already replaced the MAF but that ended up causing more codes and I have checked the vacuum lines to no avail.

i have a 2000 jetta 2.0 i am in desperate need of a new transmission. Ever since I bought the car I rarely had third gear and today on my way from southeastern PA to northwest Ohio seem to pretty much completely lost first unless I really slam it in and fifth likes to disengage every now and then unless I hold the shifter in place both first and fifth were slowly giving me problems until it got really bad after todays 8 hour drive. My transmission code is EBP, is there any other codes I can put in my car from another 2.0 or do I have to get another EBP?

I have a 2000 Pontiac grand am coupe GT with the 6 cylinder engine. It has been a very good car to me. I really like it and it "fits" me well ... and yet... it is now testing me. About a year ago the check engine light came on. The codes were P0327 and P0336 for bad Knock sensor and Crank sensor respectively. The were both replaced multiple times, the light still stays on... and the codes are still coming up. I have have been to different experts, and after the computer resets... there they are again. (someone even thought that the computer needed updated codes for those sensors... so he installed them.. with no better results). The code P1189 for an oil switch is now coming up too.Here in California, the car cannot pass smog with the check engine light on... so I'm not able to re-register it, and I don't think I can sell it for much because no one can register it now. So, what this can be? Is there some common thread between all these sensors (or a recall of some kind) that would explain this? My fear is that the computer will have to be changed at about $1000. My even greater fear is that that will still not solve the problem.

So a couple days ago i replaced the fuel level sensors in my 07 gls 2.7 liter santa fe and all was well for 2 days. I had finally driven it enough that the codes cleared from active status and the car turned off the cel. However, during the same ignition cycle the engine started missing a bit and the cel came back on and started flashing at me. Codes found now are p2187 lean bank one and p2189 lean bank two, plus p0302 misfire detected cyl 2. I've tried the carb cleaner trick looking for a vacuum leak.. but no luck. Air intake boot is good vacuum lines look good etc. What might be going on? Did i get debris in the tank and glog an injector with it? Fuel pump itself appears to be operational. No bogging down or loss of power under heavy acceleration.

I own a 1996 Jeep Grand Cherokee Laredo V8, and there has been an ongoing problem with it stalling. The check engine light is on and it reads codes about idle control sensor and 02 sensor. I spent a lot of money having both replaced, along with an processor. I had to bring my Jeep to a dealership so they could "marry" the processor to the car. The check engine light went out for about a day, then once the computer reset, light went back on. The codes still read bad O2 and idle sensor despite them being replaced.
The problem is when the car starts cold I have to keep my foot on the gas for a couple minutes or it will stall out. Once it has warmed up the car runs good. I turned the idle pin on the front of the throttle body to try to keep from having to put my foot on the gas but it still stalls. It seems like it is working better in the cold weather. My mechanic says that I may have turned the idle too far trying to fix it and that is why it is stalling.
I just want my car to run without having to warm it up every time. It wastes time and a lot of gas. Could it be something other then what I've already replaced? I don't want to keep replacing the same things and not have it fix the problem.
