OK. i still have the po134 code in my car, I read in some topic about how can I test the wires and see what´s going on.

this was the results:

1 wire with .70 v.
1wires with .05v.
1 wire with .28v
and for last 1 wire with 12v.

I dont know what could be wrong or if it is good.

it supossed to find out a wire with 5v.

I dont know what wire could be .

any comments?

 

you may have wanted to right down teh corresponding wire colors to those voltages.

 

^^ Random said that I should get a wire with 5v, i dont know what wire.

I checked every wire in the sensor connector and near to the ECU and nothing.

 

As I said before, There are 4 wires.

2 signal wires 5V+ and a ground wire

You need to hook your multi meter to the negative battery terminal, then record the voltage readings across the 4 wires with the engine running but cold, and THE SENSOR PLUGGED IN.

Then hook the multi-meter to the positive batter terminal, then record the voltage readings across the 4 wires with the engine running but cold, and THE SENSOR PLUGGED IN.

Then create a chart using those readings.
If you don't find one with 5V...then it's the ECU that's bad, like my previous post/HMA info stated.... rolleyes.gif
