about 1 year ago when driving my truck to school. The check engine light came on and I lost alot of power,turned around and went home. I did the paper clip and found a code 52 , knock sensor. Went in over time and replaced it. Put it all back together and it would not run... after a couple of months found it was the timing was 180 out and got her running.

Now after all I did, soon as I drive around for a couple of minutes the engine light comes back on and I lose all power once again. Throws the code 52 again and sometimes says no codes.

Err....

 

The wires or the ECU are the next steps in the chain I think???

Repo

 

Is it a 3VZ(3.0)? They are bad for the whole wiring harness for the knocksensor buring up just buy it from toyota and repalce it. You sould be fine after that.
