What can cause my 05 Cadillac STS to rev rpm's while I'm driving

Asked by Mar 27, 2017 at 10:44 PM about the 2005 Cadillac STS V6 RWD

Question type: Maintenance & Repair

1 Answer

Try testing the throttle position sensor, had an old nissan that would do it once it hit about 35mph. Replaced and fixed the revving issue. To test, remove sensor completely , grab a volt meter and set to ohms and attach to pins inside where the wiring connected, using a decent sized flst head screw driver slowly turn the small gear in center of tps, watch for resistance, should continue to increase as you turn it. If not, replace it. Hope this helps.
