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?
View 4 Replies2004 chevy cavalier ... when i first start up the car & put it into the drive, it acts like it's going to stall and the low traction light comes on. if i go slow enough, the light will go out, if not both the ABS and NO TRAC and the SERVICE lights will come on. i took it to a repair shop a year ago and they jiggled the wires by the left front wheel and said they'd have to look into it more since I was there for them to just check out the brakes (they were fine). after they jiggled the wires, the problem didn't happen for another couple of months. today i took it to a chevy dealer & they said i needed to replace the left front speed sensor & harness. I just got my oil changed on the way home, the usual warning lights never came on when they would doing the usual starting up and backing out of parking spots. do you think that just a wire is loose and every time i have them look at it, it reconnects?
View 2 RepliesThe 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).
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
2001 F150 5.4L Triton Motor. Everything seemed o.k. then got the Engine Service Light. Checked with reader and above codes only appeared. Read numerous articles/videos and pulled the PCV hose/boot assembly and replaced the whole thing with oem part. Visually checked for disconnected tubing = none found. After this and with the new hose assembly in place I performed a reset. With the scanner still connected restarted engine and read values: ST FTRM1&2 = -.08~+2.3, both oxygen sensor voltages are varying and the LT FTRM1&2 hang around +26 and +28.
From what I understand the ST seems o.k. but the long term is WAY OUT OF WHACK. Started it up again and took carb cleaner spray and covered all the connections I could see = no change in engine rpm. No cracks in the air cleaner body. Big plug to the MAF was inserted and plugging the hole. I am thinking of making a smoke "machine" and trying that or removing the hoses from the throttle body and plugging the holes in the throttle body and see if that clears them up. IF it does then connect one by one and keep checking the values. Lot more work but I am at a loss.
Yesterday afternoon the "Service Engine Soon" light turned on in our '97 Town & Country (3.8L engine). A few minutes later (while I headed to Autozone to get the code read) the light went out. They were still able to retrieve 2 codes: P0700 and P1775. Internet searches suggest a possible bad solenoid pack for the transmission.
More background: The van has 161,000 miles, and the original owners got the transmission replaced at 40,000 miles under warranty (4 speed automatic). The transmission fluid was replaced (pan drop method) at about 153,000 miles and at 112,000 miles, etc., with Chrysler ATF +4 fluid. The van got new plugs and wires about 15,000 miles ago. (It also got a new radiator and hoses yesterday morning which I think is unrelated.) Another possible clue: On long trips sometimes the 2nd transmission shift will become slightly rough but it still shifts and after it has rested everything returns to normal. This occasional shifting issue has been going on for over 5 years and again when it manifests itself it is very slight.
The SES light in my 2001 7.3 came on about a month ago while I was towing a light trailer in the SoCal mountains. When I got home I spent about 2 weeks replacing the injector o-rings and glow plugs. I discovered while I was in there that the head bolts on the driver's side where loose. I retorqued them to spec.
Both batteries were disconnected for the 2 weeks. When I started the truck the SES light was still on.
My Torque Pro app isn't showing any error codes, and is reading live data correctly. (I didn't have the app when the light first came on; I only purchased it after I finished the repairs). Am I missing something? Is the SES light not necessarily connected to fault codes? If so, wouldn't it reset after 2 weeks with the batteries disconnected?
I have a 1999 Ford V-10 Triton 6.8L engine with 100,000 miles in my Motorhome. Service engine soon light has been a problem for the past couple months. I have replaced the O2 sensor on the passenger side and the EGR valve. After that I drove for about 300+ miles continuously and stopped to get gas. Light stayed off and I thought I had it fixed but after starting up again the light came back on. The codes are P0171 and 0174.
I had the air filter replaced before changing the sensor and valve and mechanic left the Mass air flow sensor out of the socket I had a sluggish engine and at the time I thought I sucked water into the filter, I was driving in a pouring rain, this sensor plugs into the air intake above the filter correct?) I plugged that back in. What is my next move because I reset the service engine soon light and it runs great then the light comes back on after I shutdown and restart.
2001 01 1.8t... Hoping this isn't a bad ABS module. When I bought the car, I was told it was a bad wheel sensor in the drivers side. But, the funny part about this is its not on all the time, sometimes it doesn't even come on and the dash is normal.
View 3 RepliesThis is my daughter in laws car. The rough idle, check engine light and trac light all happened at the same time. She was in a parking lot and drove over a speed bump when all the problems started. The check engine light flashes when driving above 25mph. It's on solid at idle. I found the EVAP purge valve plastic nipple was busted off so I replaced the assembly. I was totally surprised when this had no effect on the symptoms.
I find it strange that the car was running fine and then has all these symptoms after going over a speed bump.
I purchased the vapor canister vent valve and purge valve as the service engine light has been on and this are the contributors. I want to know the location of these and how to access. It appears that they may be by the fuel tank and I don't know if I need to lift the box or something to access them. It is the 5.3L V8.
View 5 RepliesI just purchased my first foreign car ever. it is a 2002 Elantra it idles very rough changed plugs using NGK and wires new fuel filter and ran 2 full tanks of high grade fuel with STP fuel injector cleaner. but had no effect on idle also have no check or service engine light. What to check next?
View 3 RepliesTwice now (and maybe a third time once I start my van again) we've had problems with the van chugging and then the service engine light blinking. Both times it happened in the past, we took it to a mechanic who said it needed a tune-up - new spark plugs, wires, etc. I'm curious as to why this keeps happening. Mileage is around 105K. It first happened last summer, second time was in December. Now it's March. What could cause this problem to repeat?
View 2 RepliesPassengers side tail light doesn't react when braking, using hazards or blinker, what do I replace? The bulb is lit, but doesn't blink or brighten when the brakes are applied. As of right now I'm replacing the bulb socket seeing as when I replaced the bulb the contacts were covered in a brown crust, is there something else I should be looking at?
View 3 RepliesI have a 2001 1500 with the 5.3V8 motor (ext. cab sb 4x4 LT). I was my dads and had the service engine light on for a long time for the P0446 code. I replaced the vent valve and the purge valve and light keeps coming back on. Usually can go for a day or so and then it comes back on and I get the same P0446 code.
View 3 RepliesOk I've got an 01 7.3 and the scanner I'm using won't connect to the pcm. I had it remanned and put it back on still nothing. Took the idm out and swapped it for a buddies. Still nothing. All fuses are good. Scanner communicates with every other module EXCEPT the pcm. It was shutting down on my way to my mechanics place but starting right back up. Flashing wait to start and water in fuel lights. Also would shut my overdrive off.
View 6 RepliesSo, starting about 2 months ago my car started starting kind of hard and the CEL came on. It would crank for a few seconds, start to turn over but sound like it was going to sputter out, but ultimately turn over. It seemed to be exacerbated the longer the car sat between times running. I let the car sit for about a week while I was waiting for parts to come in to change out my front brakes, and now it won't start.
I hooked up my newly acquired OBD II reader and got the following DTCs:P0130 - O2 Sensor Circuit Malfunction Bank 1 Sensor 1P0130 P - Same, P for PendingP0336 - Crankshaft Position Sensor A CKT Range/PerformanceP0340 - Camshaft Position Sensor A Bank 1 Circuit Malfunction
Based on my limited understanding, I would think something having to do with the last two codes would be why the car isn't starting, but it seems like it could also easily be something else not directly indicated by those codes. So what I'm wondering is, do I need sensors replaced, or is there something else that needs to be replaced on the car. The car has ~130k on the odo.
I have a 2001 F350 and my service engine soon light came on. For a while it went on and off and every time it came on the engine ran rough and I lost some power. I pulled the valve covers and checked the UCVH and everything was fine that I can tell I even made the shims out of quarters and put them in. After putting it all back together its still doing the same thing.
View 1 Replies2001 f350 7.3 diesel and I come up with the codes for upper and lower dual generator fault. I have only one alternator not the dual.. I checked the gauge and it is running at 14 consistently. But the service engine soon light keeps coming on...I clear them and they come right back... Alternator is only 2 years old and not a rmf..
View 1 RepliesI have a 2005 Cavalier (60,000 miles) that's been having some transmission slipping in the cold weather. As the weather has warmed up, the issue has lessened but not quite gone away. We added a little transmission fluid, but I haven't yet had a chance to replace the fluid/filter. The check engine light has been on in my car since I've owned it... the shop I bought it from replaced the solenoid, but the code still hung around. Everything I've googled tells me that the issue could be the wiring or could be the solenoid needing replacing. My real question is... how soon do I need to act on this? p0741 p2761
