04 r32 CEL just came on. 1st blinking now just on steady. Timing belt, coils, plugs, wires, ecu and then some done at dealer within last 3,000 mi and still?
View 5 RepliesI have a 2011 Elantra that I purchased brand new. Has over 60,000 miles on it. Had a check engine light come about year or so ago which was fixed with a software update at the dealer.
Check engine light is back on now. Steady light; it's not blinking. Brought it to my mechanic. Ran diagnostic and said the oxygen sensor needed to be replaced. P codes were P2096 and P2196. He ordered the sensor from the dealership and installed it. Reset my cars computer. I drove the car 26 miles and the engine light came on again.
Here are my questions:
1. Wouldn't my mechanic's diagnostic equipment tell him what the problem or all the problems were? Why would it tell him the oxygen sensor needed to be replaced when there seems to be another problem causing the engine light to come on?
2. Would the dealership have more insight into a check engine light system problem than a mechanic shop may have?
Many threads on this subject, however my lights are a little different
When it first happened, on start up, I got all 4, which went away after about 1/4 mile of driving
Next start up I only have the ABS, VSC steady on and the TPS blinking. No "E brake light" lit like before and as others have mentioned.
The dash lights stay on all the time, even when shutting down and re starting. My rear brake lights work normally. Disconnecting the battery for about 30m didn't reset them either.
Lastly, I hooked up my scanner (Actron) and no codes were returned. Have the same symptoms and it still turned out to be the switch??
I have a 2000 Toyota Avalon XLS with 134k miles, engine is a v6 (3.0). It has a rough idle and a steady misfire. You can drive it sometimes and it will run perfect and you can drive it sometimes and it will misfire. I am getting codes P1150, P0300,P0302, P0304,P0306. Driving me nuts.
View 1 RepliesI did the blue wire cut-mod 20 minutes ago. I had a consistent blinking TPMS light. I cut the correct, blue, wire and grounded to a stud behind the kick panel. The light is now steadily lit. Was I supposed to disconnect the battery first?
View 1 RepliesI had a motor go bad, overheated, replaced it with another motor. Got it all back together and upon test drive I am having a low rpm (below 3k) bad hesitation/misfire. The engine runs just fine at wide open throttle.
First thing i checked for were plug wires and vacuum leaks. The only difference between the old block and the new block is the fact that i replaced the MAF with a new one, as i was getting a maf code on the old engine. I can't get it to throw a code...
So over the last couple months every couple of weeks my car throws a couple codes:
17497 - Mixture Regulation; Bank 2; Range 1: Lean Limit Exceeded
P1089 - 001 - Upper Limit Exceeded - Intermittent - MIL ON
17559 - Long Term Fuel Trim Additive Air; Bank 1; Range 1: System too Lean
P1151 - 001 - Upper Limit Exceeded - Intermittent
If I clear them things are fine for a week or two, then they return. I'm gonna check my intake, as I may not have a good seal on all the couplers (EIP CAI with the replacement for the accordian pipe). Otherwise I'm thinking injectors?
As to the noises, with the key turned to ACC ON but without turning over the engine I hear a steady ticking. It sounds like a mechanical clock, and it's coming from behind the brake fluid reservoir. During the VAGCOM autoscan the ticking noise speeds up while it scans the ABS system. There are no codes on the ABS, but I've never noticed this ticking sound there before. It it normal?
Lastly, after turning off the car I could hear a little motor. It's at the front, and after popping the hood I could hear what I assume was coolant flowing through the piping behind the radiator on the driver's side, however, the fans are not running. I assume if the coolant is flowing the car is in its cool down phase and the fans should be on at low speed. Since they aren't I'm assuming I've got the common fan issue. Does that sound right or is it normal for the coolant pump to be running without the fans?
The MIL came on (steady on, not blinking) about a month ago on a very rainy day. The car felt sluggish going from stop to start and at low speed, but then it was OK at higher speed (>40 mph). I checked the fuel cap, which was tightened appropriately. I went to my mechanic. His computer diagnosed the problem to be malfunctioning of the "throttle position sensor". I had the throttle position sensor replaced. About two weeks after the new sensor was put in, the MIL came on again and went off in two days. Two days later it came on again (steady, not blinking) after I drove to work in a downpour. This time the car had no problem getting from stop to start and at low speed, but could not go over 45 mph. I went to my mechanic again. The computer diagnosis this time was "system too lean". After three dry days when I drove only very short distances, the MIL went off. What is going on? are computerized diagnoses always accurate? why did the MIL seem to be related to wet weather? I bought a Honda Accord because of its reported reliability.
View 19 Replies2000 Jetta AEG ... An intermittent CEL light turned into a blinking CEL after a few months. Checked codes and it threw a P0303 (misfire on Cyl 3).
Pulled the plugs and found this:
There was oil dripping off of the plug from Cyl 3.
I last changed the plugs in July 2014 and only drove around 10k miles this past year.
When I changed them back then though Cly 3 looked like this:
Before I changed them back then I had an oil cooler gasket fail on the freeway and oil shot everywhere under my hood. Obviously oil is in there and it is causing problems.
I have read online and most of what I have read says that it's likely an issue with the VCG (Valve Cover Gasket) or the PCV (Pressure Control Valve) that is allowing oil to get to that part of the spark plug tube. I've also seen some non VW stuff talking about replacing the spark plug tubes.
Also it does appear that there is a little bit of oil around the threads of the other plugs but nothing getting to the all the way to the tip around the electrode.
I have pulled the plugs, wires and the ignition coil as well ... I'm ready for whatever. I am by no means a mechanic but I am capable of following instructions and doing what is needed. My problem is generally finding out what is needed to be fixed.
On my way to work, my check engine light started blinking and car was sputtering (real bad on idle). I ran the code and it came back with misfires codes. I changed the coils/plugs, fuel filter and fuel pump last year. Can the coils be bad already? When I clear the codes the car will run fine for a little while. But after a couple miles CEL will blink and the car will run roughly again.
Car : 2004 Golf 2.0
Codes:
16684: random multiple misfires
16648: fuel injector #2 short to ground
So last Thursday I started my car up in the blistering cold and it ran fine for about a minute and started to misfire so I shut it off. It hasn't ran since. When that happened the check engine light was blinking because of the misfire. I didn't have a code reader at the time to read it. now that I got a code reader the damn thing isn't throwing any codes. it spits and sputters sometimes. I've had no previous problems with the car. Thinking It might be a weak fuel pump or bad coils and in not sure how to test them.
View 1 RepliesI have a 2009 Matrix. The AC just stopped working as we were going down the road. The voltage at the compressor was 2.6 volts. the same voltage at the HVAC module I don't hear the compressor kick on at all, engine speed doesn't change when the AC button is toggled on and off.
The AC light stays on steady not blinking. I am pretty sure that there is enough refrigerant in the system.
So recently I took my engine apart to do a valve cover gasket and Ecs tuning 2.0 coil conversion. I noticed a good amount of oil in the plug tubes so I got out my trusty soap dispenser and started pumping out oil. Pulled plugs and cleaned them (wanted to make sure oil was all out b4 getting new) also while I had it apart I wanted to take intake off, ( just to polish it and clean out any carbon inside).. Well I never ended up doing that. I removed the injector connections and realized it was to much work for such little satisfaction. So I plugged the injectors back in.
I got my car all back together and now I'm throwing 6 cel codes!! P0102 (maf) which I'm assuming b.c I took it off for so long, p0201, p0202 ( injector 1 and 2 miss), then some misfire codes p0300 (random) p0301 (cylinder 1) and p0304 (cylinder 4). The car starts runs very rough then cel comes on and blinks. I was thinking maybe the oil getting down to the combustion chamber couldn't be the best for it but it would just burn off. Only other thing I did was take off the thottle body and cleaned it.
So i got two codes.... P0300 and P0305. I am thinking its the coilpacks because i changed the spark plugs a few months ago. Cleared it last week and came back today. What else could it be? And is it ok to just change one coil pack or do i have to do all of them? The recall was done in 2007.
View 3 RepliesI bought a 2001 golf gls 1.8T (AWW) about a month ago and it was running pretty bad, was throwing some codes, cylinder 1 misfire and some o2 sensor codes, I replaced the coil packs and spark plugs and then cleaned the MAF. It was still running bad ,rough idle and power loss. I figured it had to be some kind of vacuum leak, I replaced the PCV valve, cleaned the intercooler and put on a silicon TIP. Still had some rough idle and power loss, checked for vacuum leaks, using the good ole starter fluid method and found my intake manifold was leaking so I replaced that gasket. STILL rough idle and power loss, now I'm pulling codes for o2 sensor and a misfire in cylinder 3. My question is, should I replace my pre-cat o2 sensor or replace my MAF sensor? Or are there other things that should also be checked/replace.
View 5 RepliesSo my girlfriends's 2001 2.0 Golf (engine code AVH, 153k miles) began throwing codes for misfire on cylinder 4 and for the o2 sensor (post-cat) recently. I went ahead and replaced the spark plugs, wireset, and the coil pack. They were way overdue. The CEL went away for like 30 miles, and then came back. Now it's reading misfire on cylinder 3 and the same thing for the o2 sensor. What else it could be? Search is coming up blank, most people replaced the coil pack and the CEL went away.
View 2 RepliesI get some bucking under load between 1500 and 3000 rpm. This issue is more noticeable when the engine is warm. When it does this it makes a sound that to me sounds like a misfire from the exhaust, but I've never gotten a misfire code.
Sometimes i get codes p0411 and p0420 (secondary air injection and cat efficiency) but VCDS tests say my cat and o2 sensors are all good.
2005 4cyl. Vue with 54K... Steady CEL. Runs great. Absolutely no problem accelerating. Don?t hear or feel any misfiring. There is a slight rumbling sound when I first start to drive the car, but to me, the sound doesn't seem come from the engine, but rather underneath the car. It goes away when I continue to drive. Since winter began, I occasionally feel a very slight hesitation during idle?happened once or twice lately.
Again, I only feel justified in mentioning it simply because of the codes that were generated. None of my passengers have made a comment about the idle or the drive. My friend, however, made a remark that occasionally, there is a very very very slight hesitation at the downshift when braking. No crack in gas cap. Great fuel economy. No problems accelerating at all. Never hear or an actual misfire, which I take it, means a problem when accelerating, a jerking, or popping noise.
Took it to a dealer. Codes were 0300, 301, 302, 303, 304?302 generating most often. Dealer recommended new ignition module and plug replacement, but they said it wouldn?t be a guaranteed fix and that it may need EGR replacement (don?t hear knocking though) or be a burnt valve in the cylinder. No suction out tailpipe, no rotten egg smell (signs of burnt valve). What are the chances of burnt valve in a car with 54K anyway?
Also, my maintenance schedule claims that I don?t need new spark plugs until 100K. Is there anything else this could be such as a dirty injector system, fuel filter, fuel pump, or air filter? Again, overall, the car runs GREAT! Should I just wait and see if the misfire becomes more pronounced so when I take it to a mechanic, they won't be looking for a needle in a haystack?
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.
View 3 RepliesSo my daughter's 2000 Golf Mk4 with 160,000 miles on it was running rough and had 3 codes stored - cylinders 2 & 3 misfire and a 411 secondary air injection problem.
Having had the misfire code before I swapped injectors around and the error code moved cylinders with the injectors so I attempted cleaning them and also cleaned the throttle body and intake manifold. At this point car still running rough but also started smoking badly.
Replaced the following items:
- Spark plugs
- Spark plug wires
- PCV valve
- PCV hose
- Fuel injectors w/ remanufactured
Hose reconnected between secondary air injection pump and air intake - previous owner had duct-taped it in when he couldn't get it to seal I guess. I've never heard it run.
Car running better, idles more smoothly, doesn't stumble or stall like it did before, no error codes coming up BUT car smokes a lot and the fumes make me feel sick just driving it a mile.
The car had never smoked like this before, hasn't had a whole lot of love the last year or two but no real problems either so why the sudden smoke?
At first I assumed it was cleaner being burned off but that should have been gone in under a minute and this is on-going. It's bad enough to not only be embarrassing but apparently dangerous as the fumes are bad.
I have a 2004 santa fe with the 2.7L v6. I was driving and then it started to sputter and then stalled. I tried to restart, but the the engine would crank but no start. I came back to it about half hour later it started up as if there was no problem, and then after a 10 minute ride it stalled and did the same thing.I got it home and scanned it, came up with a couple misfire codes, a crank sensor code, and improper segment timing code ( I never heard of improper segment timing ). Also after fuel fill ups it never wants to start or stay running. I researched the fill up problem and found the purge canister valve to be bad. I haven't changed the purge valve yet, would that have anything to do with the stalling? If the crank sensor was bad, would it start later if it sat for a while. With my experiences when a crank sensor goes bad, the vehicle wont restart at all.
