Ford Code P2127, otherwise known as Throttle/Pedal Position Sensor/Switch E Circuit Low, is an issue faced by many Ford vehicle owners. This code is triggered when the accelerator pedal position (APP) sensor APP2 circuit voltage is less than 0.25 volts. There are several potential causes for this issue, such as an open APP2 circuit, a short to ground in the APP2 circuit, or a damaged APP sensor. Diagnosis of this issue requires an APP2 sensor PID reading to identify the exact cause. Several service bulletins related to Ford Code P2127 have been issued, such as 14-0215, 15-0036, 16-0163, 18-2062, SSM44356, SSM46829, SSM46880, SSM47432, SSM47656, SSM50116 and SSM50245.
Causes and Solutions for Ford Code P2127
| Cause | Solution |
|---|---|
| APP2 Circuit Open | Check the APP2 circuit for any open wiring or faulty connections and repair as necessary. |
| APP2 Circuit Short to Ground | Test the APP2 circuit for any shorts to ground and repair as necessary. |
| Damaged APP Sensor | Replace the APP sensor with a new one. |
| APP2 Circuit Voltage Less than 0.25 Volts | Check the APP2 circuit voltage and ensure it is greater than 0.25 volts. |
Open APP2 Circuit
The most common cause of Ford Code P2127 is an open APP2 circuit. This can be due to faulty wiring, corroded connections, or a broken wire. It is important to check the APP2 circuit for any open wiring or faulty connections and repair as necessary.
Short to Ground in APP2 Circuit
Another potential cause of Ford Code P2127 is a short to ground in the APP2 circuit. This can be due to faulty wiring, corroded connections, or a broken wire. It is important to test the APP2 circuit for any shorts to ground and repair as necessary.
Damaged APP Sensor
The third potential cause of Ford Code P2127 is a damaged APP sensor. This can be due to wear and tear, or the sensor may be faulty. If the APP sensor is damaged, it should be replaced with a new one.
APP2 Circuit Voltage Less than 0.25 Volts
The last potential cause of Ford Code P2127 is a low APP2 circuit voltage. This can be due to faulty wiring, corroded connections, or a broken wire. It is important to check the APP2 circuit voltage and ensure it is greater than 0.25 volts.
Conclusion
In conclusion, Ford Code P2127, otherwise known as Throttle/Pedal Position Sensor/Switch E Circuit Low, can be caused by various issues, such as an open APP2 circuit, a short to ground in the APP2 circuit, a damaged APP sensor, or a low APP2 circuit voltage. Diagnosis of this issue requires an APP2 sensor PID reading to identify the exact cause. Professional repair or maintenance services are recommended to solve Ford Code P2127 issues.
