Toyota Camry (XV70): Torque Sensor Zero Point Adjustment Undone (C1515)
DESCRIPTION
This DTC does not indicate a malfunction. The power steering ECU (rack and pinion power steering gear assembly) stores this DTC when it determines that torque sensor zero point calibration has not been performed.
When the IG terminal voltage is below 8 V, torque sensor zero point calibration cannot be performed.

INSPECTION PROCEDURE 1. INSPECT CAMSHAFT TIMING GEAR BOLT
(a) Check the stroke of the plunger in the center of the camshaft timing gear bolt.
Standard Stroke: 4.5 mm (0.177 in.) or more HINT: When pressing the plunger, there may be a stepped feeling. This is not a malfunction.
