Golf IV / Jetta IV :: 2000 - CEL On / OBD Scanner Won't Read Codes
Jun 14, 2016
The past week, the CEL of my Jetta 2000 was on, and a couple of days after, was off. But yesterday was relit. I take my car to Auto Zone to check codes with scanner, but was impossible read any code, the lector can't connect with computer. I thought in fuses, but the fuses are fine.
Searching on google, i found that the reason could be the aftermarket radio, but I am not sure about that, the connections are seen aparently fine. I Read in one thread that disconnecting the aftermarket radio harness is enough to can read codes from computer.
I read also that the scanner could be incompatible with VW cars, but I don't think that, because AutoZone should have a scanner compatible with most of the common cars models.
The fact is that I don't want to get in troubles with the harness of radio, I don't have tools like multimeter neither knowledge about electrical systems, i just want to know if disconnecting the radio harness is enough in order to read codes. (in case of the problem be on the K-line wire).

I got a Passat 2000 OBD-II scanner won't read for emissions testing. I did the test in 5 different place all the time when they ask to turn the key and the computer from emission test give a error and stop.
I have a radio aftermarket one of my friend have this problem and he have to install the original radio. So I buy the wire harness and the radio i install and still not able to do the emissions test.
My ABS light is flashing but my friend said this is not a problem he fix more than 4 car just replacing the aftermarket radio....

My 1999 super duty v10 has thrown a code but my scanner and a mechanics scanner won't power up and read the code, I also noticed that the cigarette lighter is dead. Which fuse controls both the plug and the lighter?

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.

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?

My daughter's 2000 Jetta with a 2L has an engine light and codes that state Misfire on 1 and 4. It is intermittent as it only misfires once in a while.. She is in Rolla MO, and I am in Detroit MI. A couple of years ago the car died when she was home and I found a swollen/cracked coil pack. I replaced it with an aftermarket. The plugs and wires were replaced about 30k ago with OEM parts. I am tempted to have the son in-law replace the coil pack with a Bosch unit.

I have a 2001 cavalier with the service light on. i hooked up my scanner but there are no codes. My daughter recently wrecked it and knocked out the passenger side headlight and turn signal. Will the service light come on if a bulb is out?

My 98 Corolla won't start, but I have checked battery, fuel pressure, spark, efi relay, and fuses, which are all good. Can't figure what to fix?
Have connected a pocket scanner but I get no codes.

The Prius has 115ooo miles. It is a 2005. Just recently it started showing the red triangle of death, check engine light, and the brake light. When I check for codes using a scanner it comes with the following:
P0A80
C1310
C1259
P3015

Bought a Mk4 1.8T gti last year had only about 75,000 on it and drove it for about 10,000 miles. The check engine light went on about 2 months ago and the code read 3rd gear incorrect ratio. It still rode fine until about a week ago when it started slipping. Brought it to the local transmission guys in my town and got a quote at about $3,000-$3,500 to have the transmission rebuilt. The transmission is a tiptronic automatic 6-speed.

I have a 2002 Alero 2.2 4 cyl and the gauges, head lamps in auto position, windows, fan, and radio will not come on. When car is off and key turned to acc. radio will work. It still drives ok, doesnt seem to be draining the batt but the check engine light came on. I took it to autozone and they COULD NOT read the codes and didn't know why.
The speedometer, temp and fuel gauges haven't worked for months now and the rest of the accessories not turning on is a recent issue.
The only thing that comes on regularly is the backlight for the dashboard and now the check engine light. I had the ignition switch replaced right before the speedometer, fuel and temp gauges stopped working. I noticed tapping the key sometimes gets the radio, windows, and fan working but not the dashboard gauges. Don't want to replace the ignition switch again since it doesn't seem to do anything for the dashboard gauges.

Today I bought an OBD2 scanner and was trying it on my 2001 accent but the app on the cellphone ( torque ) said : " couldn't connect ECU " . I think there is no ECU in my car, any example about trying the OBD on a 01 accent ?

Bought a used Prius 2010 last december, Now the hybrid system is shut down and the assumption is that the hybrid battery is the culprit. No codes has been read out of the system but the car has passed 330 000 km so I guess that's very plausible. Have found a used battery from a 2009 prius who the local Toyota service facility says is compatible.

I have a 2006 Chrysler Sebring Convertible 2.7L engine. Replaced water pump and spark plugs. We triple checked the alignment on the chain and are sure the timing is fine. Car started right up. Now running rough idle and engine light comes on. Codes read misfires on 1, 3, and 5 cylinders.

Have a 2000 F-150, 5.4L. Once recently in a parking lot, it would crank but not fire or start. Wife called me to come get her. By the time I got there, she said it started "after she loosened the gas cap & re-closed it." But, it started fine for next several weeks. Yesterday it didn't. I read a bunch of threads here on possibilities. Many troubleshoot items I checked out or had done.
Chilton manual says you can get limited error codes from the light on dash flashing - MIL - Malfunction Indicator Lamp Method.
For now, I'm trying to find the 2nd, separate, one-wire lead "near or with the (main) Diagnostic Connector." They call the single wire / connector the "Self-Test Input connector" (STI). You're supposed to use a jumper between that STI & the upper, right connector of the main diagnostic connector. Then you (may) get flashes corresponding to codes via the key on, engine off method.
I see no such single wire lead or connector anywhere near there. Not up under the dash either - stuck my head under there & used mirror. There's a separate connector (not in use) clipped on the L side of the main diagnostic connector, but it has 5 pins inside. I took pics, but forum says I "may not post attachments." Been a member for yrs. That extra 5 pin connector faces toward firewall.
There's an "empty hole" - 1/4 in. (facing forward) in the bracket that holds the main diagnostic connector. Just above the main connector. Not sure if something was ever there
If no one knows how / if the Malfunction Indicator Lamp Method works or where the jumper goes, I'll be forced to buy a code reader w/o researching which are decent or crap (around $200 or less). I maybe? could wait to order one online (if knew which one). Also have AutoZone, O'Reilly, Advance, NAPA, PepBoys & others locally.
* The truck shows a check engine soon light, so should be a code already. * Yes, I tried her loosen / tighten gas cap trick.
* Also put a slow charger on for a while & even used the fast start setting on charger. No go, but engine turns really fast.
* Crawled under the gas tank & listened for fuel pump to activate when key is turned to Run.
* Fuel pump made a small noise - more like a relay or "clicking" - not a whine or whir.
* Checked most fuses - under dash & hi voltage box - that have anything to do w/ fuel pump, PCM & several others - mentioned in similar threads here.
Can't really check relays & don't want to just start replacing parts. I don't have a code reader & reluctant to buy one from local store w/o some reasonable research. (I don't mind buying one, but...). If I could drive it to the auto store, I wouldn't be asking this. Chilton's doesn't say if this malfunction indicator lamp method will work if a vehicle won't start. But, a code is already thrown.

I got a 2001 Escape XLT (V6) a couple of months ago. Its in great condition, only 82k miles on it too. It had the notorious door handle issues which I have had fixed. It also had the wet weather stuttering problem, which I had fixed by having all 6 spark plugs replaced (Motorcraft OEM plugs), the back 3 coils replaced, upper intake gaskets replaced, Valve cover gasket replaced, PCV valve replaced (motorcraft).
It runs great when its warm, the problem I am having is when its cold outside and the engine is cold, it starts up fine but idles like crap and if its really cold outside, it starts and dies 3 or 4 times before it can even get to the crappy, stuttering idle. I have to intermittently feed it gas to keep the cold idle going long enough (3 or 4 minutes) before I can drive it. Once the engine is warm it drives like a champ. The only warm engine issue, is occasionally after driving it and putting it in park, the engine will rev up to 2000, 3000+ rpms, and just keep going up until I shut the engine off.
The codes read P0171 and P0174, which are lean on bank 1 and bank 2. It had also thrown a misfire on cyl 6 but once I cleared that it hasn't come back, just the lean codes are still present.
From what Ive been reading, this can be a number of issues, ranging from the IAC valve, EGR valve, MAF or the lower intake gaskets. I'm very much a rookie when it comes to car mechanics, but I think I can handle changing the IAC, EGR and MAF since they are all on top of the engine. However I don't know if I could handle the lower intake gaskets. Ironically, the gaskets are the cheapest part, but the most labor if I paid someone else to do it.
If I replace the EGR, do I also need to replace the EGR Modulator as well? Looking for brand names that are best bang for the buck when it comes to these other parts I have mentioned?

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

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.

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.
