P0225

Diagnostic Chart:

Wiring Diagram:

CIRCUIT DESCRIPTION
The Accelerator Pedal Position (APP) module provides a voltage signal that changes relative to accelerator pedal position. There are three sensors located within the APP module that are scaled differently. This is a type D DTC.

CONDITIONS FOR SETTING THE DTC
- Reference voltage on APP 3 below 4.8 volts.
- Condition met for 2 seconds.

ACTION TAKEN WHEN THE DTC SETS
If DTC P0225 is present, the Powertrain Control Module (PCM) will turn ON the Service Throttle Soon lamp and limit power.

CONDITIONS FOR CLEARING THE MIL/DTC
- A History DTC will clear when forty consecutive warm-up cycles that the diagnostic does not tail (coolant temperature has risen 5°C (40°F) from start up coolant temperature and engine coolant temperature exceeds 71°C (160°F) that same ignition cycle.

DIAGNOSTIC AIDS
All 5 volt reference circuits must be checked for proper reference voltage. Voltmeter accuracy is important.

TEST DESCRIPTION
Number(s) below refer to the Step number(s) on the Diagnostic Table.

2. This Step will check all 5 volt reference circuits.
