It is an indication that limp mode/failsafe mode has been activated. There is a myriad of problems that can cause P2106. The throttle actuator itself is rarely the … Read more
Modern vehicles use knock sensors to detect engine detonation. This allows the PCM (powertrain control module) to run very aggressive spark timing. If you are concerned that your Mitsubishi Eclipse has a bad knock sensor, we’ve listed them out below. A knock sensor works by listening to your engine and determining if your Eclipse is … Read more
No matter where you live if your Mitsubishi Eclipse’s AC compressor is not turning on, it can turn a pleasant commute into a nightmare (particularly if you have kids that are riding with you).
