2005 Acura Timing Belt Replacement Causing P0389 Code - VSA and MIL Lights On
I recently replaced the timing belt and water pump on my 2005 Acura, but now the engine warning light (MIL) and VSA lights are both illuminated. The diagnostic code reading is P0389. I attempted to reset the system, but the code returns immediately after. I've double-checked all timing marks and confirmed they are properly aligned. I'm seeking expert advice on how to resolve this issue without further damage.
It's possible that during the timing belt and water pump replacement, you disturbed a sensor or wiring harness. The P0389 code relates to the fuel pressure regulator circuit, so ensure all electrical connections are secure and properly seated. Refer to official Acura service documentation for troubleshooting steps related to P0389 in 2005 models.
