What is engine code P0327?
OBD-II Code P0327 is defined as a Knock Sensor #1 – Circuit Low Input (Single Sensor or Bank 1) The purpose of the knock sensor is to alert the PowerTrain Control Module or PCM that the engine is pinging or knocking.
How to test the p0327 knock sensor low input?
Vehicle is setting a DTC P0332 and P0327 for low or insufficient knock sensor activity from sensor 1 and 2. Tests/Procedures: 1. Disconnect the Blue Powertrain Control Module (PCM) connector and check resistance value on Light Blue wire at pin 11 for sensor two and Dark Blue wire at pin 51. Both of these should be on the Blue PCM connector.
What does the DTC code p0327 stand for?
What Does the P0327 Code Mean? Diagnostic trouble code (DTC) P0327 stands for “Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor).” It is triggered when the powertrain control module (PCM) detects very low voltage readings from your vehicle’s primary knock sensor circuit.
How to get p0327 p0332 to go away?
-Replaced both knock sensors and the wiring harness, properly cleaned and torqued etc. -BOTH pending codes P0327 and P0332 come up within a couple minutes of running after every time I reset them. (Yes, they are plugged in, it’s the first thing I checked!!
What does trouble code p0332 mean on a car?
When the engine “knocks” there is an excessive amount of NOx that is released. When trouble code P0332 is set, the Power Control Module (PCM) has received a reading from knock sensor 2 in Bank 2 that is too low, and it will not be able to accurately send a ping to correct a problem.
What causes a p0327 knock sensor circuit low input?
Potential causes for a P0327 DTC include (but are not limited to): 1 The knock sensor is faulty and needs to be replaced 2 There is a wiring open/short/fault in the knock sensor circuit 3 The PCM/ECM has failed
What Does the P0327 Code Mean? Diagnostic trouble code (DTC) P0327 stands for “Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor).” It is triggered when the powertrain control module (PCM) detects very low voltage readings from your vehicle’s primary knock sensor circuit.
What does the p0332 OBD-2 trouble code mean?
What the P0332 code means. The knock sensor’s purpose is to signal to the PCM when the engine is pinging. If the PCM is receiving a reading from the knock sensor that is too low, it will not be able to accurately send the appropriate signal of a ping, and the PCM will not be able to correct the problem.
