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.
Nathan, 2 Knock's are located under intake manifold.

code p 0327 refers to knock sensor (KS) 1 bank 1---low input===causes ---insecure KS, poor connection---wiring short to ground---incorrectly tightened---KS---ECM
check all the wires for good connections and the fitment of the KS
replace the KS if all other items check out ok
This trouble code has to do with the knock sensor on your vehicle. Lower votage is detected by the vehicles computer. If you need further information, you can reply here or feel free to email me directly at [email protected] and I'll be happy to try and help.
code p0 refers to intake air temp sensor --circuit malfunstion causes are wiring open circuit(broken)wiring short to ground bad earth and ECM. code po113 refers to mass air flow( MAF) sensor/ volume air flow (VAF) sensor --low input. Causes may bewiring short to ground MAF?VAF sensor faulty ECM code po327 refers to Knock sensor (KS) bank 1--low input. Cause may be insecure (loose) KS poor connection- wiring ---short to ground incorrectkly tensioned KS and ECM
The P0327 means Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor). the knock sensor is located in the front of the engine located behind the oil dip stick just to the left. _______________ Ktag K-TAG
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.
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.
