P1125

DTC P1125 ETC (Electric Throttle Control) Limit Performance Mode

Wiring Diagram:

Circuit Description
- The acceleration position (AP1) sensor circuit provides a voltage signal relative to acceleration pedal angle.
The acceleration pedal angle will vary about 13 % at idle position to about 87 % at wide open throttle (WOT).
This code detects if the system is in Limit Performance Mode (Fail safe Mode) and Multiple DTCs Performance Mode.

Conditions for Setting the DTC
- The Ignition is " ON".
- Limit Performance Mode is active. (Fail safe Mode)

Action Taken When the DTC Sets
- The PCM will store condition which were present when the DTC was set as Freeze Frame and in the Failure Records data.

Conditions for Clearing the MIL/DTC
- The PCM will turn the MIL "OFF" on the third consecutive trip cycle during which the diagnostic has been run and the fault condition is no longer present.
- A history DTC P1125 will clear after 40 consecutive trip cycle during which the warm up cycles have occurred without a fault.
- DTC P1125 can be cleared using the Tech 2 "Clear Info" function or by disconnecting the PCM battery feed.

Diagnostic Aids
An intermittent may be caused by the following:
- Poor connections.
- Misrouted harness.
- Rubbed through wire insulation.
- Broken wire inside the insulation.
Check for the following conditions:
- Poor connection at PCM - Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals,And poor terminal to wire connection.
- Damaged harness - Inspect the wiring harness for damage. If the harness appears to be OK, observe the APP sensor 1, APP sensor 2, APP sensor 3 display on the Tech 2 While moving connectors and wiring harnesses related to the sensor.

A change in the display will indicate the location of the fault.

If DTC P1125 cannot be duplicated,the information included in the Failure Records data can be useful in determined vehicle mileage since the DTC was last set.

If it is determined that the DTC occurs intermittently,performing the DTC P1125 Diagnostic Chart may isolate the cause of the fault.
