Hello, I need some help. I have a 1996 Honda Civic ex (automatic) D16y8 VTEC engine. Today I had a mechanic replace distributor with a new one (not rebuilt) from an auto parts store. The mechanic did not...


Yes, the ignition timing could be off enough to cause the symptoms and the check engine light.
I would take it back to the shop and tell them to set base timing, clear the code, and refund you the cost of the knock sensor and labor.

My 2000 yukon knock sensor code came up. the shop said $ 700 to replace. the 5.3 motor runs great. Does this need replacing?


the engine has two knock sensors they are mounted under the intake manifold, $700 sounds a bit high , i think i would price around, as to the question do you have to replace them, NO, but they are there it aid in the ignition control if the engine spark knocks these sensors are there to sense this. and also if one of the sensors is always reading as if the engine is spark knocking then the on-board computer will keep trying to ****** the timing and this will effect you power, and fuel millage.

How much will it cost by removing snd replace knock sensor and catalytic convertoer? both parts and labour.


It will be two hours labor, the knock sensor is around $40.00, the converter is hard to say, but could be up to$400.00, this all depends on where you take it. A dealer is giong to cost more on parts and labor, than a private shop

Service soon light stays on.. had it checked at auto zone and came up with po327 knock sensor condition. Is this gona be an expensive car repair?


no, 30 minutes labor--you can do it yourself. part is $30. You have 2 of them. 327 is for bank 1, which is the back bank by the firewall. see picture below (the picture is bank 2, but location is same on other side).

To replace the knock sensor:
  • Disconnect the knock sensor wiring connector.
  • Then, unscrew the sensor.
  • Remove the knock sensor.
  • Reverse the procedures to install the part.

      A defective knock sensor may cause engine detonation or reduced spark advance and fuel economy. When a knock sensor is removed and replaced, the sensor must be tightened to its specified torque. If the knock sensor is installed tighter than it should be, it may become too sensitive and provide an excessively high voltage signal, resulting in more spark ****** than required. When the knock sensor is installed looser than it should be, the knock sensor signal will be lower than normal, resulting in engine detonation.

    I have an engine code PO332 knock sensor 2 circuit low imput bank 2 what is this problem .the car is a 2001 gmc yukon xl .


    The most likely cause of your code is a bad rear knock sensor. You should check the knock sensor wiring harness for corrosion. But if that checks out the sensor will have to be replaced. The knock sensor is under the intake manifold, although it's not too difficult to remove. Both knock sensors should be replaced along with the wiring harness, just because of labor involved in gaining access to the sensors. You could try clearing the code, it may stay off for a long time.

    I would change the mass air flow meter firstly.If your knck sensor was the problem then you would have engine running rough.If its not causing any problems when driving then its safe to drive with the light on.

    TRUCK STARTS OCCASIONALLY, WHEN IT WON'T START I HAVE NO SPARK & NO FUEL INJECT, INTO TBI, REPLACED ECM,USED OLD CHIP, ALSO REPLACED COIL,KNOCK SENSOR,FUEL RELAY,IGNITION SWITCH AND IN TANK FUEL PUMP


    I have a '99 suburban and had the same problem. Couldn't figure it out. Took it to the dealer, and it was a engine disable type module. There is a sensor in the ignition switch that "sees" the key (connected to this module), and allows the engine to start/run. Could be the sensor or the module. My problem was the module. Seem to remember costing about $500 with troubleshooting, parts, labor. Good luck.
