TPS fails on 07 Ranger 700. NO error codes are present. The UTV starts and does not respond to throttle. Replaced TPS, UTV runs great for a very short time and failure returns. Polaris warrantied the TPS, replaced, worked great again for very short period then became unresponsive again.
NO error codes present at all. I haven't peeled back and and inspected the entire harness, but wiring looks good at TPS/harness connection and all places on UTV that are usually places of failure and breakage. I would think wiring to be the prime culprit, but visual inspection shows wiring in very good condition. They install and dial-in easily. but then stop working. I even had the dealer re-flash the computer. Battery new and fully charged.
What would cause these TPS failures?
