Lexus Vibration, Tapping or Misfire After Cold Soak

Lexus Vibration, Tapping or Misfire After Cold Soak

Here are the steps to follow if experiencing vibration, tapping or misfire after a cold soak in a Lexus.

Models:

2013-’16 CT200H

Symptom: 

Some CT200H vehicles may exhibit a vibration due to a rough idle or tapping noise from the hybrid transaxle after a cold soak. The check engine light may be on with codes P0300, P0301, P0302 or P0304 stored in the ECM. 

Correction: 

Lexus has released new software for the ECM to resolve the condition. If the vehicle has already been serviced for this condition, there will be a sticker affixed under the hood. After the vehicle is reflashed, allow the vehicle to cold soak to confirm that the problem is no longer present.
