The check engine light came on so i got a readout to see what was causing the check engine light to come on. It said the knock sensor was bad so I replaced it and the car ran great for 2 days then the check engine light came back on and once again it is tellling me the knock sensor is bad. Seeing how I need to eliminate the check engine light in order to pass a CA.smog test in order to register the vehicle //which is due very soon\\ I need to resolve this issue. Any suggestions?

Testing for bad sensor is simple 1 WITH THE KNOCK SENSOR STILL CONNECTED CONNECT A VOLTMETER BETWEEN THE (TERMINAL 3) YELLOW /GREEN WIRE AND A GROUND SOURCE 2 TURN IGNITION ON 3 TAP THE ENGINE CROSS MEMBER OR A PART OF THE CAR ATTACHED CLOSEST TO THAT AREA WITH A WRENCH 4 VERIFY THERE IS A VOLTAGE SPIKE LESS THEN 1VOLT FROM THE KNOCK SENSOR 5 IF THERE IS NO VOLT SPIKE YOU HAVE A BAD SENSOR ALSO YOU CAN RUN THE ENGINE AND LISTEN FOR YOUR SELF OF ANY UNUSUAL SOUNDS COMING FROM THE ENGINE SUCH AS SOMETHING LOOSE /BAD HARMONIC BALANCER / MISFIRE OR SPUTTER/ PULLEY NOISE OR WATER PUMP IF IT IS GOOD SOMETHING IS BANGING WHEN DRIVING AND SETTING IT OFF WHEN YOU READ THE CODE IF YOUR SCANNER WILL ALLOW CHECK AND SEE AT WHICH POINT IT IS THROWING THE CODE MOST LIKELY ITS AT COLD START CHANGE THE SPARK PLUGS AND REPLACE WITH OEM PLUGS ONLY GOOD LUCK Edited April 11, 2014 by loaderXI Link to comment Share on other sites More sharing options...
