What causes a p 0327 diagnostic code on a 95 contour


P0327 - Knock Sensor 1 Circuit Low Input Bank 1 or Single Sensor
First check the knock sensor connector. If the connector is clean and secure, replacing the knock sensor usually takes care of the problem.

- An excessively low voltage from the sensor is sent to Powertrain Control Module (ECM) or Engine Control Module (ECM)

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Powertrain Control Module (PCM) or Engine Control Module (ECM).

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power

Possible causes
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- Faulty Powertrain Control Module (PCM) or Engine Control Module (ECM).


Test and check it. Hope helps.

WHAT IS ENGINE CODE PO332?


The knock sensors (KS) produce an AC signal when specific frequencies are detected. When the engine operates, the powertrain control module (PCM) learns a minimum and maximum frequency of noise of normal engine operation. The KS system monitors both knock sensors in order to determine if knock is present. If the KS system determines that excessive knock is present, the PCM retards the spark timing based on the signals from the KS system. The PCM then retards the timing until no knock is present. When the PCM detects a frequency that is less than or more than a defined range, DTC P0327 will set for a failure in KS 1 which is located on bank 1 on the drivers side of the engine or DTC P0332 will set for a failure in KS 2 which is located on bank 2 on the passenger side of the engine.
But, the problem doesnt have to be the sensor, it could be bad ignition coil, bad spark plugs, bad/no/too much Fuel.......

My 2004 Buick Rendezvous service engine light is on. Advanced Auto ran diagnostics and P0327 & P0336 was listed on the diagnostics. The car misses here and there. I also have to try to crank the car...


P0327 Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor). This is mounted right on the block with a pigtail connector attached to it. Easy to replace and cheap.

The hard starting is caused by the
P0336 Crankshaft Position Sensor. Again, not overly difficult.
