P1227 NISSAN - Accelerator Pedal Position Sensor 2 Circuit Low Input
P1227 NISSAN Possible Causes
- Faulty Accelerator Pedal Position (APP) sensor
- Accelerator Pedal Position (APP) sensor harness is open or shorted
- Accelerator Pedal Position (APP) sensor circuit poor electrical connection
How do I fix code P1227 NISSAN
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Cost of diagnosing the P1227 NISSAN code
Labor: 1.0The cost of diagnosing the P1227 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P1227 NISSAN code detected?An excessively low voltage from the Accelerator Pedal Position (APP) sensor 2 is sent to Engine Control Module (ECM).
P1227 NISSAN Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1227 NISSAN MeaningThe Accelerator Pedal Position (APP) sensor is installed on the upper end of the accelerator pedal assembly. The sensor detects the accelerator position and sends a signal to the Engine Control Module (ECM).
Accelerator pedal position sensor has two sensors. These sensors are a kind of potentiometers which transform the accelerator pedal position into output voltage, and emit the voltage signal to the ECM.
In addition, these sensors detect the opening and closing speed of the accelerator pedal and feed the voltage signals to the ECM. The ECM judges the current opening angle of the accelerator pedal from these signals and controls the throttle control motor based on these signals.
Idle position of the accelerator pedal is determined by the ECM receiving the signal from the accelerator pedal position sensor. The ECM uses this signal for the engine operation such as fuel cut.
