Have VSS code PO501. Have fitted new right vehicle side speed sensor, after reset code clears but quickly returns so still got code. Speedo is working. Have sent ECU for testing - no faults found.
Car is an auto, can the left/drivers side sensor cause this or the transmission sensor cause this?
Have a 2000 Passat V6 5spd. Recently ran the codes, and this is what I came up with under engine.

Do these components share a common ground, or connector, I imagine it is a simple fix. just wiggle fuse, or ecu connector?
The check engine light came on in my 1997 Honda Accord and the OEM diagnostic says it's PO501 which is a performance problem in CVT speed sensor circuit. My mechanic is on vacation. Is it safe to drive short distances until I can have it fixed?
View 7 RepliesThe check engine light on my 09 Corolla came on so, after it continuing to stay on, I bought a OBD ll Code Reader. The scan showed 10 faults but, only 3 code numbers were given for the 10 faults. Each of the 3 code numbers appeared twice for a total of 6 out of the 10 faults indicated. The remaining 4 faults had no corresponding code numbers. Don't know why but, they just didn't. Even after multiple scans.
Here are the code numbers that did show.
P2401(twice)
P2402(twice)
P2419(twice)
According to the CD that came with the reader, this is what the codes mean.
P2401.. evap emission system leak detection pump control circuit low.
P2402.. same thing as above except control circuit high.
P2419.. evap emission system switching valve control circuit low.
Looking for more specific explanation to me what this all means then it has something to do with emissions. Is it something that should be of concerned? I have erased the codes a couple of times but after a day or two, the engine light comes on again. This has been going on for over a month now but, the car is working great. Last road trip, I got approx 52 mpg.
I have a 2006 5.4L F150. I am encountering a misfire on the #3 plug. The only OBD error messages I receive are from misfire on #3, no other faults.
I have checked the plug, and it looks pretty good. I have recently changed all COPs. I have removed the injector rail and checked and cleaned all injectors. I have removed the wire connector from COPs and checked the voltage while the vehicle is running.
The #3 connector is measuring around 13.6V ... The other COP connectors I measure 0.17V to 0.4V ....
It appears this low volt reading is due to the neg signal wire closing and opening. I brought it in to a mechanic and he indicated the computer needs to be replaced, no signal was getting to COP. So this appears where I am at.
I have hence gotten a LED test light and verified the other COP connector wires cause the test light to flash, while the #3 COP wire connection to just stay on all the time, no blink signal. What the problem is?
The engine sounds pretty good, maybe a slight tick sound. But the misfire wobble is apparent. I figure I will change the computer at this point, since it appears this is where the issue is.
What else could interfere with the COP neg signal? It is pretty clean in the engine compartment, and no visible problems with the wires fraying on the accumulator, as I have read reports happening.
Is it the cam that makes this negative signal wire open and close?
Threw a random CEL, took the car to Pep Boys, Code P0036 was found "Oxygen Sensor Heater Control Circuit Bank 1 Sensor 2. What I should do and risks involved if I do not take care of it soon?
View 3 RepliesMy prius 2010 (III) accelerate much slower than before. I started noticing this after I picking up my car from the airport. Parked the car there for a week. I have the dealer checked the computer but no error codes found. My car has almost 250k KM on it. I have not replaced the spark plugs the last three years. Could it be the spark plugs?

What happened,,,kids was driving car, had 3 phones plugged in, ac, lights, and when she tried to set cruise, car went into limp mode, gear lights flashing,,,went into neutral,,,stop beside highway,,had to be towed.
12 volt battery charged and tested ok. no blown fuses. I reset ECU by jumping pins 14 and 4. no change, tried master reset by holding brake and power button down, no change..removed ecu fuse to reset, no change.
I have a 2007 hyundai accent 1.6 l gls, recently got a code p0496 and installed a purge valve and 4 days later got a code p0497 (evap emission sys. Low purge flow). Would it be better for me to take my car to an emission shop where it can be diagnosed since i do not want to take to dealership cause the cost would be very high. I want to diagnose it with some machine that will pinpoint the main problem without me replacing parts just to find out that maybe the part i thought was bad did not need to be replaced.
View 2 RepliesI am getting a poo12 code on my 2007 hyundai accent. All the sensors seem to be fine. How to get it fixed?
View 9 RepliesRecently got broadsided (passenger), got the body fixed up. Now it is Misfiring on idle and only on idle...
Prior to this I had Coil go out on me, got that changed out, changed the spark plugs. It was running great then the accident happened an this Misfire on idle problem.
Took it to the shop, had them check for a code, no code. They suggested that it made be do to carbon buildup from the previous misfiring issue and suggested using STP engine treatment on it.
This is in regards to a 2007 Accent 111k miles, about 3 weeks or so .. I had a p0420 code, and replaced the downstream o2 sensor, and the CEL went off, and gas mileage went up. Now today I got p2096 code. Seems to mirror the p0420 code. So now I am thinking the catalytic converter.
So my questions are:
There are two catalytic converters right? one would be the exhaust manifold and the other would be half way through the exhaust system after the two o2 sensors?
Which should be replaced in regards to p2096?
Could anything else be causing this code?
Sudden power loss experienced. CEL (Check Engine Light came on) and Glow Plug Light was flashing. Power loss is severe so really can't drive it anywhere. Turbo Failed at 5500 miles.
Mechanic quote: "Found code P0299 for turbo power under boost. Removed upper engine cover and intake hose. Checked turbo shaft and found play near intake side of turbo. Removed lower engine shield and lower hose to intercooler. Checked for metal. Contacted VW and created VTA. Instructed by VW to replace turbo. Did."
Sounds like service manager abbreviated when entering into the computer. In any case a shame that this car was in the shop for more than a week while the dilly dallied and waited for a turbo to be shipped in.
Some earlier turbo-fail threads from last summer stated dealer told them "bad batch" of turbos was being experienced by VW. Believable, particularly if they're banged out in China? Let's all hope it was a bad batch.
I have a 2005 prius and I got a scanguage to read the codes. I have two lights on my dash. One is the check engine and the other is the (O) light. I think this is something to do with the regen braking. Anyways when I run the scanguage it says no codes found. What type of scanner would be able to pull up all prius codes?
View 6 RepliesMy check engine light has been on for months and the only code coming up is for the VSS. I got the VSS replaced and the light came back on as soon as I hit 70 on the freeway. Checked the code again and the same one came up. Is this a common issue with 06 Accents? I'm wondering if it might be a wiring or computer issue... My ABS light is also on, would this have anything to do with it?
View 5 Replies2009 Accent, 1.6L 154,xxx Cylinder two misfire. Engine was rebuilt due to timing belt. Twice. Second time I did it. Replaced plugs, coil packs, all gaskets, (everything new in the head) did a smoke test, compression test 180 psi across all four, used a noid light for coil packs (good) did it at the injectors 1,3,4 did good, but 2 came on then went off. Check resistance and it shows good, replaced injector anyway and the connecter. Still doesn't work. Checked powers and grounds at the rail, good. Good solid voltage. I hooked up a scan tool and tried to shut injector 2 off, no change in RPM or vibration. Scan tool worked for 1,3,4. Used another PCM, still misfire in two. Even jumped a wire from PCM control and 15A inj fuse for the 12V constant (bypassed the harness) and still doesn't work. Also have knock sensor code, just two codes.
View 14 RepliesTwice today my car stalled out while idling. Once at a left turn red light and once in the drive thru. The first time it restarted after about 10 minutes. The second time it restarted after about 2 minutes.
Car is throwing cod P0339 for Crankshaft Position Sensor A Circuit Intermittent.
I did some reading up on this on the forums but didn't do much about it. I just tried wiggling the wiring and all that when idling, didn't notice any roughness or stalling so.... may not be a connector issue.
Anyhow, planning to take it in for diagnosis and repair as it's really not derivable the way it is.
Actually this is the first time ever the car has given me engine trouble of any kind. just passed 90,000 miles. Shucks, streak broken.
I have a 2010 accent GL manual sedan. It has 104,962 KM on it, the warranty expired December 18, 2015. Since February this car has become a frustrating money pit. Being in the dealership constantly for repairs, then within a week something else 'happens' and back it goes. Spent almost $5000 in 4 months on repairs. Decided that's enough and will do majority of repairs myself.
Yesterday while drive on the highway I had a sudden loss of power and a check engine light came on. My scanner which has become a standard item in my glove box indicated a misfire on cylinder 2 - P0302. I limped the car home, in 3rd gear I was having a hard time staying above 2000rpm at 60km/h. at lights I had to use hand brake so I could keep my foot on accelerator, revs were dropping below 300.
Today I replaced all the plugs (all 4 were still in good or better condition, #2 showed signs of a slightly rich burn and #3 a slightly lean burn), replaced all coil boots (no cracks, no burns, and still pliable), removed and cleaned all the injectors. Error code P0302 persists.
I have a 2008 Hyundai Accent that is giving me one heck of a headache. I keep getting a code for number 1 cylinder misfire. When you start it up it runs fine for a while then the CEL will flash and it will start running rough. As soon as I shut it off and restart it, it runs fine. I even experimented with it this morning on the way to work. It started running rough doing 60, I put it in neutral, turned the car off and then right back on, put it back in gear. It ran fine the rest of the way to work. I have swapped coil packs, fuel injectors, spark plugs, and have even hang tested another ECM. Still number 1 cylinder misfire.
View 8 RepliesP0420 bank 1 code popped up while driving. Im thinking this is just an oxygen sensor? Is it ok to drive with this code for a while if i buy an o2 sensor online?
View 5 RepliesWhen looking at the engine from the front of the vehicle. what numbers are the cylinders from left to right? To curtail off of that question where do I locate the corresponding ignition coils to these c I have been dealing with intermittent misfires on cylinders 1 and 3 codes P0300, P0301, P0303. I replaced the spark plugs to no avail. Whenever the vehicle shudders the headlights dim and the shuddering is worse when the vehicle is placed in gear, the A/C fan is on, or the vehicle is accelerating. Once I reach a certain speed, usually 35-40 mph, I don't notice until I again slow down. I replaced the spark plugs the day after I had the first issue appear which read code P0301. Prior to installing the spark plugs, I experienced a severe loss of acceleration power, but now only experience the shuddering.
