Diagnostic Aids

WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

If DTCs P0110, P0115, and P0120 are also set, malfunction may be in the sensor ground circuit.
On a good TP sensor, scan tool will typically display a TP angle of 8-10 percent at idle, and 76-77 percent at Wide Open Throttle (WOT).
An intermittent malfunction may be caused by fault in the TP sensor electrical circuit. Check wiring harness and components for an intermittent condition. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES - 1.8L VIBE article.
Repair any electrical circuit faults found.
Information included in freeze frame data can be useful in determining vehicle operating conditions when DTC first set.
