Tech Tip: Lexus MIL On With DTC P0335 and/or P0340 Due To Low Battery Voltage

Applicable vehicles: 1994 and later models (non-­hybrid and hybrid).

Condition:

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 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 the cause and repair accordingly.

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

• The freeze-frame data example (Fig. 1) indicates battery voltage was only ~6.3 volts when DTC P0335 was set.

Wheel Bearing Adjustment Tools & Equipment

A wheel bearing that’s out of adjustment can reduce bearing life and can affect more than just the bearing. It’s important to adjust the wheel bearing endplay to the proper specifications. If the bearing set is adjusted too loose or too tight, it can cause the bearing to fail prematurely. There are a few types of assemblies, so using correct procedures and tools will ensure a comeback-free wheel bearing installation.
