Hi Guys
I could use some help regarding a low TPS output signal.
The output V is less than 1.2v at WOT.
With the harness disconnected at the TPS the ref. V is 5 v which is good.
With harness disconnected and the ignition off I have 1.2 ohms at the TPS ground wire on the harness side which is good.
However, with the ignition turned on I have 25 ohms resistance at the same wire, which would be present when the motor is running likely causing an issue.
How can this be?
Thanks in advance
