C1796 Toyota Code - Front Acceleration Sensor Right Malfunction

Quick Answer

The acceleration sensor (up and down G sensor) detects the upward and downward acceleration of the vehicle and outputs it as a voltage to the Suspension Control ECU. Common causes include Faulty Front Acceleration Sensor Right, Front Acceleration Sensor Right harness is open or shorted, Front Acceleration Sensor Right circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1796 Toyota Description

The acceleration sensor (up and down G sensor) detects the upward and downward acceleration of the vehicle and outputs it as a voltage to the Suspension Control ECU. Up and down G sensors are installed in 3 locations: 1) the Suspension Control ECU, 2) the driver side instrument panel, and 3) the passenger side instrument panel. Each up and down G sensor independently detects the upward and downward acceleration. During a test mode inspection, the Suspension Control ECU reads the fluctuations in the signal of each sensor. When the sensor cannot detect +/-1.96 m/s2 for 1 second or more during the test mode, the Diagnostic Trouble Code (DTC) is stored.
