Review on Enhance Performance with Standard Motor Products APS147 Accelerator Pedal Sensor! by Wes Thao

I bought this part because my 2007 TL gave error P2138 "Throttle position sensor - Incorrect voltage correlation". The car went into limp mode and stayed in fourth gear until restarted. Replacing this part was fairly easy; It's at the top of the firewall on the passenger side. After replacing this part, the error code was gone and I no longer had these issues. Throttle sensitivity has been greatly improved and the car drives much better. This is a good replacement at a significantly lower price than the OEM (although both parts are identical to the same manufacturer listed on the site).
