2010 cobalt code po327 .have put on new sensor. light still comes on


knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor on Bank #1 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0327 DTC. This P0327 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0328, P0329, P0330, P0331, P0332, P0333, and P0334.

I have a 99 oldsmobile bravada 4.3 jasper engine new with 61k and the service engine soon light came on and read a po327 knock sensor code Please tell me how to fix it and where its located on the engine


Hi, this code could indicate a wiring issue or a problem with the sensor itself. A new sensor is about $40. The sensor is on the back of the engine as shown in the picture below. If you have an ohmmeter, I recommend you check the continuity of the wire from the sensor to the computer. The computer is in the passenger side door pillar. Locate connector B, pin 19. You do not need to disconnect the computer to check continuity of the wire. Just probe the back of the connector at the dark blue wire, pull the connector off the sensor, and touch your other ohmmeter probe to the terminal in the knock sensor connector. There should be one ohm or less resistance in the wire. If resistance is higher than one ohm, repair or replace the wire. If resistance is good, unscrew and replace the sensor. Please let me know if you have questions, and thanks for using FixYa.

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.
