Code C1420 Scion Description
The C1420 diagnostic trouble code (DTC) for Scion vehicles indicates a malfunction in the acceleration sensor. The acceleration sensor is a crucial component of the vehicle's stability control system, as it measures the rate of acceleration and deceleration of the vehicle. This information is used by the vehicle's electronic control unit (ECU) to adjust braking and engine power to maintain stability and control during acceleration and braking.
Common Causes of C1420 Scion
- Faulty acceleration sensor
- Wiring or connection issues in the acceleration sensor circuit
- Corrosion or damage to the sensor's connectors
- Electronic control unit (ECU) malfunction affecting the sensor readings
Symptoms of C1420 Scion
- Loss of traction control functionality
- Increased difficulty maintaining control during acceleration and braking
- Illumination of the traction control or stability control warning light on the dashboard
- Erratic behavior of the vehicle during sudden acceleration or braking
How to Fix C1420 Scion
- Diagnose the issue by connecting a diagnostic scanner to retrieve the specific error codes and sensor data.
- Inspect the wiring and connections of the acceleration sensor for any signs of damage or corrosion.
- Test the sensor's functionality using a multimeter to check for proper voltage and resistance readings.
- Replace the acceleration sensor if it is determined to be faulty or malfunctioning.
- Clear the error codes and perform a test drive to ensure the issue has been resolved.
Cost to Fix C1420 Scion
The cost of repairing a malfunctioning acceleration sensor can vary depending on the specific make and model of the vehicle, as well as the labor rates in your area. On average, the cost of replacing an acceleration sensor ranges from $150 to $300 for the part alone. Labor costs can add an additional $100 to $200, bringing the total repair cost to around $250 to $500. It's important to note that these are rough estimates, and actual costs may vary based on individual circumstances. It's recommended to consult with a qualified mechanic or auto repair shop for a more accurate cost estimate.
