Low Scion batt fools sensors
This bulletin applies to Scion hybrid vehicles. A low battery voltage can contribute to a MIL on condition for P0335 (crankshaft position sensor) and/or P0340 (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 below the minimum spec, determine the cause and repair accordingly. If battery voltage was within specification, refer to the appropriate repair manual procedure for the applicable DTC.
