Celica Forums General Discussion General Need some advice

As some of you know my CEL came on a little bit ago. I got the code pulled and it could be any of the following...

1. Hose or tube cracked, hole, damaged or loose seal.

2. Fuel tank cap incorrectly installed

3. Fuel tang cap cracked or damaged.

4. Vacuum hose cracked, hole, blocked, damaged or disconnected.

5. Fuel tank cracked, hole, damaged.

6. Open or short in vapor pressure sensor circuit.

7. Fuel tank over fill check calce cracked or damaged.

8. ECM

Now i was wondering how you would go along checking the vapor pressure sensor and vacuum hosing. Any advice is appreciated.

Thanks

Wow, that's crazy stuff. Check the gas cap first.

Reset the ECU & see if its a fluke or if its a real problem.

ok thanks, i'll try that.

probably have a bad gasket on your gas cap. A whole new cap is like $12, pick one up. Might fix it, might not, either way it's a good item to replace.
