Code P0873 2011 Toyota Camry Description
The P0873 diagnostic trouble code (DTC) for a 2011 Toyota Camry indicates that there is a high voltage condition in the Transmission Fluid Pressure Sensor/Switch 'C' circuit. This sensor is responsible for monitoring the pressure of the transmission fluid and sending this information to the vehicle's engine control module (ECM). When the ECM detects a high voltage signal from the sensor, it triggers the P0873 code.
Common Causes of P0873 2011 Toyota Camry
- Faulty transmission fluid pressure sensor
- Damaged wiring or connectors in the sensor circuit
- Malfunctioning ECM or TCM
- Low transmission fluid levels
- Contaminated or degraded transmission fluid
Symptoms of P0873 2011 Toyota Camry
- Erratic shifting or delayed gear changes
- Harsh or rough transmission shifts
- Transmission slipping or jerking
- Illumination of the Check Engine Light
- Reduced fuel efficiency
How to Fix P0873 2011 Toyota Camry
- Diagnose the issue using a scan tool to retrieve the trouble codes and perform a thorough inspection of the transmission fluid pressure sensor and its circuit.
- Test the sensor's voltage output and resistance to determine if it is functioning correctly.
- Inspect the wiring and connectors for any damage, corrosion, or loose connections. Repair or replace as needed.
- Clear the DTCs from the ECM memory and reset the system to see if the code returns.
- If the issue persists, consider replacing the transmission fluid pressure sensor or seeking further diagnosis from a professional technician.
Cost to Fix P0873 2011 Toyota Camry
The typical repair costs for addressing the P0873 code in a 2011 Toyota Camry can range from $200 to $500, including parts and labor.
