This bulletin applies to 1994 and later Lexus models, including both non-hybrid and hybrid). Low battery voltage can contribute to a MIL-on for P0335 (crankshaft position sensor circuit) and/or P0430 (camshaft position sensor circuit) due to inconsistent rotational speed of the crankshaft.
Review the vehicle’s freeze frame data and verify if the battery voltage was below the minimum specification of 11 volts when the DTC was set. If battery voltage was low, determine the cause and repair as needed.
