This problem applies to vehicles with OBDII trouble codes P-0161, P-0155, P-0135, and P-0141.

This is an amateur presentation, offered in good faith, for free, but with no guarantees as to accuracy or safety. Never rely on a single source for critical information, and read widely from multiple sources before committing to a pathway. Auto repair comes with inherent danger. Be sure you have the skill set and experience to tackle this kind of job before proceeding. Any misadventure you encounter if you decide to accept the risk of DIY repair is your responsibility.
