Wondring how to troubleshoot the TPS, replaced the harness and ECU and now getting the check engine light to flash 7 times, I believe that faults is a open or short in the TPS. Wondering where to start.
Check your connections for corrosion or condensation, had the same problem with mine and after going through everything else we sprayed some electrical cleaner on the ECU plugs and put some dielectric grease on em before plugging back together and no more problems.
