The chain tensioner maintains the appropriate tension in the chain. The tensioner can use spring tension or hydraulic pressure to properly tension the chain. Symptoms of a bad or failing chain tensioner include: engine may stall or run rough, noise in the front of the engine (a rattle or rumble, associated with engine speed), or check engine light may illuminate and set misfire, camshaft sensor, and crankshaft sensor codes.
