Diagnostic Aids
WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2002 Lincoln Town Car, 2002 Lincoln Navigator, 2002 Lincoln LS, 2002 Lincoln Continental, and 2002 Lincoln Blackwood. However, it is still accessible from the selected car via links, so may be relevant.
Perform this test only when directed by QUICK TEST. This test is intended to diagnose the following:
- TP Sensor
- Binding Or Sticking Throttle Linkage
- Wiring Harness Circuits (PWR GND, SIG RTN, TP, VPWR & VREF)
- Powertrain Control Module (PCM)
Normal range of throttle angle measurement for TP sensor is 0-96.6 degrees. To pass QUICK TEST procedure, range of throttle rotation (in degrees) must be within 3 percent of specification. To prevent replacement of good components, be aware the following non-EEC related areas may be at fault:
- Idle Speed
- Binding Throttle Shaft Or Linkage
- TP Sensor Not Seated
