I was just driving and the engine check light appeared. The screen says Emission workshop. its a 2001 B5 passat V6 Manual. I used a code reader and it read P1120 and P0154. Are these codes serious? Can I still drive around? What should I do?
View 4 RepliesI have a 2002 Prius that needs work. The red triangle, PS, and check engine light are all on. It has these codes:
P3100 - 175 (HV ECU internal error. Motor Inverter Current Sensor Malfunction)
p3125 - 287 (Motor Inverter Finv. Inverter Internal Short)
c1259 (HV System Regenerative Malfunction)
I suspect the inverter or even worse the MG2 has burnt windings.
BTW the "infamous" inverter pump seems to be working. I can hear it and see the fluid in the reservoir move.
I suspect it is more a symptom than a problem and will disappear when the real problem is fixed.
I have a 2006 passat and the check engine light came on so I performed a scan, the results are below. fault codes... which ones would need to be repaired immediately?

Check engine light came on yesterday evening. Advance read the codes as P0100 and P0171. The guy said something that it may be related to the mass air flow sensor. The car seems to run fine.
View 2 RepliesOk so we have yet again the engine light on...we did a test and we have the codes P2004 and P0642. What can it be the problem this time??? what can cause this codes and is it expensive to fix? We just fix the care a couple of weeks ago( codes P0507 and P0171) and we are sooo tired of having problems.

p0431 /16815 bank 1 below threshold??

Cat? or 02 sensors???
The check engine light on my 1999 1.8T Passat is on. It started with a little miss right after startup. Then in neutral, after revving the engine to say 1,500 rpm and letting off the gas, it would nearly stall. I plugged in an OBDII analyzer and came up with codes P0102 MAF or VAF circuit low input and P0304, Cylinder #2 misfire. I replaced the spark plugs, as they were old anyway. Still the same symptoms. Then I replaced the mass air flow sensor.
The check engine light still went on after it was cleared, except this time it was P0302, Cylinder #2 misfire, P0102, P1613, Auxiliary inputs aux. outputs control, and P1426 Mfg. Control/auxiliary emission controls. Soon after, the car started running fine on it's own and I again cleared the codes.
Then a day later, the check engine light is on. This time, it is only the P1426 - Manufacturer control auxiliary emission controls. The Bentley manual calls it Tank Vent. Valve Open, which doesn't mean anything to me and the Bentley manual is of no luck. (The error code almost implies that it is the famous loose gas cap, but I have checked that - unless the gasket is bad). FYI: I have 99K miles on the car.
This morning I started my car and it was idling a little rough. The the Check Engine light began flashing - I immediately turned off the car and consulted this forum and my father the mechanic. After talking with my Dad and telling him that the car had sat for a week, he thought the issue was probably NOT the catalytic converter and thought it was probably related to the car sitting and possibly getting moisture in the gas. I started the car again (the roughness at idle seemed to have gone away) but the check engine light/malfunction indicator light (MIL) did not flash, it did come back on after a few seconds, but as a solid light . And as we've all read, it's OK to drive with a solid MIL.
I took the car over to Autozone and had the codes checked - P0300 (multiple cylinder miss fire) and P0301 (cylinder 1 misfire). I asked them to clear the codes. I has just put in new NGK spark plugs last month, so I didn't think it would be the plugs. I looked at a new coil pack for one of the cylinders. I decided to see if clearing the codes alone would work and drove home. No issues so far, no MIL, no rough idle, no hesitation (fingers crossed).
When I called the stearleship - they recommended I have the car towed, but would not speculate as to what the flashing MIL could be (catalytic converter or bad coil pack(s))...
I have a '99 durango with ~45000 miles. Recently it has been breaking down on me. I feel it lose power until it dies all together. After about 20 minutes it will start again. This has happened 5 times. When it happened today, I was going about 30 mph, when I felt it lose power. The speedometer went to '0" - the 'check engine light came on', the 'fuel pump' light came on (like it does when you run out of gas), then I had this odd message on the odometer that said "NO BUS".
This time I had it towed w/o trying to crank it with the hopes they can get a code. I told them about the "no bus" message but they did not seem to know anything about it. I have found this mentioned on a few bulletins boards but not with much info.
I own a stock 2008 Prius.
My car didn't move for 1-2 months so I needed a boost this morning. I noticed there's the check engine light on and a red triangle.
Also, the car won't go on electric mode.
Started up our 2010 RX 350 and there was loud knocking. This smoothed out after several seconds. I stopped engine and started it again. This time the knocking was less severe, but now the Check Engine light is on. Engine seems to be running a little rough as well. I have a feeling I have a bad plug or wire maybe.
View 2 RepliesThe "check engine soon" light appeared yesterday on this nice running 1997 van with 167K. An auto parts store code check indicated a problem with the oxygen sensor. Is this something I can replace myself--a lightweight shade tree mechanic? I never seem to have any luck asking questions on the Mopar website.
View 10 RepliesCar dumbie back again with another question.The diagnostic for my check engine light indicates numerous cold start misfire codes. The cylinders are OK. That was checked during the diagnostic.The fuel intake is carboned up. It is recommended that I clean the intake manifold. Does this mean cleaning the fuel injectors, the throttle body or both? 2006 Passat VW....
View 1 RepliesI just bought a 2006 prius. It had 2 bad cells in the battery pack. I replaced the cells and all seems to be well, they all read the same voltage and the car appears to be driving, charging, working.
I still have the red exclamation mark and check engine light. The only code I get says to replace hybrid battery pack.
There are no other specific codes or issues and it runs perfect. Basically I guess what I am asking is how to clear the light or figure out why the light is still on!
My 07 3.3 SF is throwing P0154 and P0300 codes. Autozone said the P0154 is Bank 2 pre-cat O2 sensor. But exactly which one? The P0300 is random misfire. Could they be related?
View 7 RepliesI have a new (to me) 2007 3.3 Sonata w/ 64XXX miles on it. Recently it set off codes for P2A03 and PO154 indicating a problem with the front upstream o2 sensor. Before I replace the sensor I was wondering if these codes might have any other underlying cause.
Symptoms: The car has recently had one instance of pulsing acceleration and one incident where it didn't want to turn over but after an extended start finally started; this problem has not repeated. Otherwise the car has strong acceleration smooth idle and drives fine.
Also, I would like to know if o2 sensors are covered by mandated emission warranty or by Hyundai's 10y/100,000 warranty.
Recently my daughter's 2004 Accent will die out without warning usually at stop lights, and will be hard to restart, usually after numerous attempts. It will crank over fine. This has been very intermittent. I have checked for fault codes, there are none. I haven't been able to really determine the cause because I have not duplicated the issue. I have replaced the fuel control module located on the driver side kick panel after reading about problems with this module, but it did not remedy the issue.
View 4 RepliesMy '05 Prius check engine light has been on for a while now, at first it would turn on for a while then turn off but now it is staying on. I took it to AutoZone and they ran a diagnostic and it returned the codes P1121, P1123, P1150, P1116.
View 1 RepliesI have a 2010 Tiguan and the check engine light has come on. When I use my ODB scan tool it doesn't find any codes and the check engine light won't go on. What might be the problem?
View 5 RepliesI have a 2002 volvo S60 2.4T that I just had the check engine light come on so I pulled the codes and here is what I found,
PO403

So my question is what does this mean ? what is wrong ?
I've had a 2005 Prius for almost 2 year and 50,000 miles now and had no problems. Recently I decided to do an inverter recall and them some "necessary" maintenance (TB, transaxle fluid, etc). How I have an intermittent CEL, P1112 (Intake air temp sensor) coming on every other day. Before I thought Autozone had another DTC detected (1121 It had something to do with a coolant stacked too high?)
What are the most common check engine light (CEL) or DTC codes and how to deal with them?
