03 Ranger 4.0 with CODE P0068
I've cleared the code twice(with a scanner) but it comes back after a couple weeks. Any ideas what is causing the code. My Haynes manual doesn"t list it. Thanks Scott

P0068 - Throttle Position (TP) Sensor Inconsistent with MAF Sensor
The PCM monitors a vehicle operation rationality check by comparing sensed throttle position to mass air flow readings. If during key ON engine running self-test the comparison of the TP sensor and MAF sensor readings are not consistent with calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
Possible causes:
- Air leak between MAF sensor and throttle body
- TP sensor not seated properly
- Damaged TP sensor
- Damaged MAF sensor
