1. DTC P2127 description
The accelerator pedal position sensor is installed to the accelerator pedal. The sensor consists of 2 sensors in 1 housing. The ECM uses the accelerator pedal position sensor to calculate the desired acceleration and deceleration. Accelerator pedal position sensor 2 has the following circuits.
- 5 V reference circuit
- Low reference circuit
- Accelerator pedal position sensor 2 signal circuit
Accelerator pedal position sensor 2 sends signals related to accelerator pedal angle changes to the ECM via the signal circuit. If the ECM detects an excessively low signal voltage, the DTC is set.
2. Condition for setting DTC P2127
Condition for running the DTC
- The battery voltage is 9 to 16 V.
- The ignition switch is ON.
- DTCs P060B and P0651 are not set.
Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 without DPD) DTC P060B Internal Control Module A/D Processing Performance".
Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 without DPD) DTC P0651 Sensor Reference Voltage 2 Circuit".
Condition for setting the DTC
- The ECM detects that the accelerator pedal position sensor 2 signal voltage is 0.4 V or less.
3. Action taken when DTC P2127 sets
- Euro4: The ECM illuminates the MIL. Refer to Action taken when DTC sets - Type A (Euro4).
- Except Euro4: The ECM illuminates the check engine warning light. Refer to Action taken when DTC sets - Type A (Except Euro4).
Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 without DPD) DTC type definitions".
- The ECM inhibits the cruise control.
4. Condition for clearing DTC P2127
- Euro4: Refer to Condition for clearing the MIL/DTC - Type A or Type B (Euro4).
- Except Euro4: Refer to Condition for clearing the check engine warning light/DTC - Type A or Type B (Except Euro4).
Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 without DPD) DTC type definitions".
