C1442 2018 Toyota RAV4 Code - Invalid Data Received from Acceleration Sensor

Code C1442 indicates "Invalid Data Received from Acceleration Sensor," meaning the vehicle's stability control system is receiving incorrect or erratic signals from the acceleration sensor.

Common symptoms include the ABS or traction control warning lights illuminating, reduced traction or stability control functionality, and potentially erratic braking behavior.

The code is typically caused by a malfunctioning acceleration sensor, poor electrical connections, damaged wiring, or issues with the ABS or stability control module.

While the vehicle may still be drivable, it is not recommended to ignore this code as it can impair the stability control and ABS functions, increasing the risk of losing vehicle control in certain conditions.

A mechanic will use a diagnostic scan tool to confirm the code, inspect the acceleration sensor for faults, check wiring and connections, and verify proper function of the ABS and stability control systems.

Repairs may involve replacing the faulty acceleration sensor, repairing damaged wiring or connectors, or reprogramming/updating the ABS module if necessary.

The acceleration sensor, also known as the G-sensor, measures the vehicle's lateral and longitudinal acceleration to assist the stability control and ABS systems in maintaining traction and control.

The cost can vary, but replacing an acceleration sensor typically ranges from $200 to $500, including parts and labor, depending on the shop and location.

Clearing the code without addressing the underlying issue will likely result in the code returning and may compromise vehicle safety systems.

This code is not extremely common but can occur due to wear and tear on the acceleration sensor or related components over time. Regular maintenance can help prevent such issues.
