hi, like the tittle say I get different voltages, the TPS plug reads .45v and when I measure in the ECU pin d11 I get .39v

This is acceptable or need to check for open wire?

dfanatic86

are you back probing pins 2+3?

Lizardslap

check it at wot it should go .48 to 4.5v if not adjust its well worth your time

Yes, D11 + D22 at ECU plug = .39v

TPS plug middle red wire + battery neg.= .45v

Lizard I not having problems with the TPS calibration, it increase and decrease flawless without spikes or death spots.

Only a slight difference in volts between sensor plug and ECU plug.

Wha are the resistance readings of the wires?

carlos8

how I measure the resistance in this wires?

Set the voltmeter to RES. negative prove to battery neg. and positive prove to the wire to be tested?

carlos8

TPS resistance.

1 + 2 = .66

2 + 3 = 4.84

Also I have low voltage between d17 + d21 = 4.0v with the MAP disconnected instead of 5.0v

I think my ECU is fried.
