Check Engine Light

[jesusm1]

hi

My car has the check engine light on , and since any physical defect I see or hear, I believed that one of the two oxigen sensors is bad. So I changed both, reset the error (disconnect the battery) run the car several times and the check engine light will display again . What could be wrong?

How many miles are on your Paseo and when was the last time you had a MAJOR tune up? Is it running rough at all or consuming more gas? Let me know all the details...

[jesusm1]

thanks for your reply:

My Paseo has 141k. At 60k and 120k I replaced the timing belt and seals. Right now is running fine. Soft starting like new. No abnormalities when the engine is idle.

I'm the first owner and I very proud of the service my Paseo brings me.

Any help will be fully appreciated

Have you tried your engine control module? How about new plug wires?

[jesusm1]

mmm.... I never changed the spark plugs wires before....

Do you think that the ECM could be with problems?

Do you know if Toyota vehicles have a way to get the error codes without a scanner (ie as pontiac when the check engine blinks several times by shorting two points on the diagnosis tester connector)?

Change the wires, check the ECM, and I'm not sure about that code thang...
