Signs of failure include: a check engine light with a knock sensor code, a reduction in power because the ECM has put the engine into a conservative timing map, or audible pinging under load that the ECM is no longer correcting for. Replace a faulty knock sensor to protect the engine and restore full performance.\u003c\/p\u003e\n\u003cp\u003eWalker, part of Tenneco, manufactures exhaust systems, catalytic converters, and mufflers.
