What does a P0121 diagnostic code for a 2003 Jeep Wrangler?
P0121 = TPS Voltage Does Not Agree With MAP sensor signal. That likely means the TPS (throttle position sensor) has gotten dirty inside and is sending out an erratic voltage the computer doesn't like. The usual fix for this is to replace the TPS which is a fairly easy "one-banana" job. The TPS cannot be cleaned when it goes bad, it can only be replaced.
