Hello,

Have a Toyota engine 1G FE. THe Timing belt was recently replaced and the ingine was running fine. Following day a water hose not properlly fitted back broke and the tempurature guage shot up and I turned off the engine. Tried to crank the engine so that I move about 10 meters to a better parking but engine failed to start (was advised this was because there was no water). Hose fixed, added water, now on cranking, the engine was idling rough but after a few seconds it was up and running. Now th problem is that After starting the car and driving for say a KM the engine check light turns on, This could be because of two reasons

1. The Timing belt wasn't fixed right and needs checking however after the timing belt fixing, the light should have come on but it didn't.

2. The spark plugs were fouled when I tried to crank with no water.

Please advise on what the problem could be

Thanks

Hi there,

Neither of these I feel is you problem, you will have to get the codes out of the ECU as this will indicate what the problem is, go get a scan and report the codes here.

Hello Mark,

Thanks for your response. Took it to the auto shop and the code was "P1346". Thanks

Take it back to the work shop that did the cam belt, this can be a cam timing problem.

Hello,

I took it back and the timing was ok. Is there anything else that ca cause this code? The guy at the auto store suggested the Oil Control Valve aka VVT Solenoid could be dirty. He cleaned it, and I changed the oil. Still the Engine check light come on. Further more the VVT sensor would show on at high RPM on the ECU reader and off at low RPM, is that normal? Thanks

The solenoid will pull in at a set rpm, I would have to check what it actually is, if you need to know, but that is normal. You may now have to start checking for a bad electrical connection, loose pins in the cannon plugs, corroded pin terminals, I would be looking here now.

Hello,

All the eletricals were checked and everything is fine. I'm beginning to think it's a problem of a poor quality timing belt, or the timing itself. See I'm in Uganda and here it's hard disern original from fake. Anyway the p1346 error comes on when going uphill. I imagine at that point the way the engine's working it streches the belt a little and engine senses an error. Otherwise I'm going to get an original belt from the toyota dealership and redo the timing. What'd you guys think of this route. Thanks

This is worth a try, but I feel that the problem will be with the sensor or the solinoid, but as a first action ensure that the valve timing is correct first.
