Adamw Posted August 8, 2020 Report Share Posted August 8, 2020 Is it the auto tps? The manual one isn’t a tps, only a idle switch. Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 8, 2020 Report Share Posted August 8, 2020 So did you cut the original wires from the old TPS connector on the housing and connect to the new pig tail plug? Where did you get the sensor ground from? Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 8, 2020 Report Share Posted August 8, 2020 As far as I know the TPS connection on the pigtail connects to the transmission, not to the ECU. So you will need to swap the signal wire from the old idle switch (I dont know what colour it is but it goes back to pin 18 on the ecu) into the other plug - I assume the center position.

Adamw Posted September 1, 2020 Report Share Posted September 1, 2020 You need to find the wire on the idle switch that goes back to pin 18 on the ECU, then move it from the idle switch to the centre pin of the TPS. Quote Link to comment Share on other sites More sharing options...
