Low battery voltage can contribute to a MIL “ON” condition for P0335 (Crankshaft Position Sensor Circuit)
and/or P0340 (Camshaft Position Sensor Circuit) due to inconsistent rotational speed of the engine’s
crankshaft.
RECOMMENDATIONS
Review the vehicle's Freeze Frame Data (FFD) 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 specification, determine cause and repair accordingly.
e If the battery voltage is within specification, refer to the appropriate repair manual procedure for the
applicable DTC.
e The following Freeze Frame Data example indicates battery voltage was only ~6.3 volts when DTC
P0335 was set.
