Chris Posted March 31, 2004 Report Share Posted March 31, 2004 I just got a PO26 today. On the drive home (heavy rain), the SES light came on. I checked codes and sure enough... P026 = Shorted Throttle Signal Switch What exactly is this and where is it located? Thanks! -Chris Link to comment Share on other sites More sharing options...

loucar1 Posted April 2, 2004 Report Share Posted April 2, 2004 A P026 code is a shorted TPS sensor (thottle position sensor). This is an easy fix/ RR. Any other codes shown? Lou 94 Seville STS Link to comment Share on other sites More sharing options...
loucar1 Posted April 2, 2004 Report Share Posted April 2, 2004 The TP Switch is part of the ISC motor and should cycle from lou to hi when the accelerator is depressed. Check your manual for the Switch action Lou 94 Seville STS Link to comment Share on other sites More sharing options...

STYES Posted April 9, 2004 Report Share Posted April 9, 2004 The TPS can be checked with a volt meter, key on, ignition off. It is a powered circuit. Back probe into the wires. Manually move the throttle. it should read, in even graduation, next to zero volts, up to about 4.6 volts, and it should be in a consistent, incremental fashion. The TPS is basically a variable resistor, or rheostat. Link to comment Share on other sites More sharing options...
