  • Charcoal canister is clogged, loaded with fuel or with moisture
  • Fuel filler cap missing, loose (not tightened) or the wrong part
  • Fuel tank over-fill check valve cracked or damaged
  • Fuel tank seal leaking, fuel tank cracked or damaged/leaking
  • Fuel vapor hoses/tubes blocked or restricted, or fuel vapor control valve tube or fuel vapor vent valve assembly blocked
  • Vacuum hose or tubing cracked, damaged or disconnected
  • PCM has failed
onepx.gif Engine started cold (ECT sensor signal less 86�F), engine runtime over 20 minutes in closed loop, vehicle driven to a speed of 55-60 mph, and the PCM detected the fuel tank pressure indicated the same value as the atmospheric pressure in the EVAP Monitor test.
This code sets in 2 Trip(s).First I would try making sure the gas cap is tight. You need to give it 2 trips before it may reset. The other choice would be to replace it, Cheaper than spending money on a professional.

I have a 1998 lexus es 300.my check engine light is on and just today the trac light came on.often when im driving mainly after getting off the highway the car will begin to shake.if I'm sitting @ a light...


I had a 94 sunbird and when we stopped, it would start running a little rough and the speedometer on the dash would start raising up sometime to 20 mph, and the car was not moving. I finally took it to a shop and they said it was the voltage regulator which was built into the alternator. They changed the alternator and we never had the problem again. The speedometer on the car was controlled by and electric circuit not a cable. You should have the code checked it can help diagnose the problem. Most auto part places where I live will tell you the trouble code for free with their code reader.

"Check the engine" light is on


You can still drive it. But, it's something that should be look into as soon as possible. It could be a small thing, or something leading to a big thing.
There are many reasons why the check engine light comes on.
Best thing to do is take to an autoparts store. Most of them will pull the trouble code from the on-board computer for free.
They should tell you what the codes mean. If they can't, come back here to this post and I'll go over them with you.

VSC/ Check Engine Light


My 2000 Lexus GS 400 just had the VSC/VSC off light and the check engine light come on. I would have to push the accelarator peddle all the way down to get it to go. Took it to the Toyota dealer and the code pulled up as the Throttle Position Sensor was out. Purchased one and having it put in. Will update if this fixes the problem.

The first and last code are your start and stop so you can ignore them the P1130 and P1150 are your two front oxygen sensors( pre cats ) bank one and two. Depending on your millage it sounds like it is time for a little maintence. Normally they should be changed at or around 60,000 kms

Engine Light


The check engine light has nothing to do with the oil, water etc. it signals that a fault has occurred in the engines electronic controls and it has failed a test of some system that the cars computer runs every few minutes while the engine is running, it can be one of a 100 different systems that made the light come on, take the car to a Kragen Auto parts store or another chain parts store like it and ask them to run a OBD 2 system test (it's free), this will retrieve the trouble code(s), post the code(s) back on this thread and I will explain what it will take to repair.
