lucriffault Posted March 21, 2022 Report Share Posted March 21, 2022 I was following a guide to reset my tps/isc because my '88 is idling around 1300. Got to step 4 and didn't notice any "zip" and the multimeter showed a constant 4.6 volts the few times I retried instead of the .9 volts it is supposed to show. Is there anything I can do besides go through looking for exposed wires that may be interfering? Quote Link to comment Share on other sites More sharing options...
TexasQuest Posted March 23, 2022 Report Share Posted March 23, 2022 Make sure the wires on the servo motor are in good condition and not corroded or damaged. That's been a common problem found when trying the TPS/ISC reset. Quote Link to comment Share on other sites More sharing options...
