Low Battery Bugaboo

This bulletin applies to 2008 Lexus LS460 models but can also apply to all 1994 and later models (hybrid and non-hybrid). Low battery voltage can contribute to a MIL on condition for DTC P0335 (crankshaft position sensor circuit) and/or P0340 (camshaft position sensor circuit), due to inconsistent rotational speed of the crankshaft.

Review the 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, determine the cause and repair accordingly.

If battery voltage was within specification, refer to the appropriate repair manual procedure for the applicable DTC.
