Knock sensor for 2007 Saturn outlook. I can't pass emissions test!


Check engine light on ? What code ? There are many different (DTC'S) - diagnostic trouble codes that can set for knock sensors ! There all don't mean that you replace the sensor .
DTC P0324: Knock Sensor (KS) Module Performance
DTC P0325: Knock Sensor (KS) Circuit Bank 1
DTC P0326: Knock Sensor (KS) Performance
DTC P0327: Knock Sensor (KS) Circuit Low Bank 1
DTC P0328: Knock Sensor (KS) Circuit High Bank 1
DTC P0330: Knock Sensor (KS) Circuit Bank 2
DTC P0332: Knock Sensor (KS) Circuit Low Bank 2
DTC P0333: Knock Sensor (KS) Circuit High Bank 2

The knock sensor (KS) system enables the control module to control the ignition timing for the best possible performance while protecting the engine from potentially damaging levels of detonation. The sensors are located below each cylinder head on the engine block. The KS produces an AC voltage signal that varies depending on the vibration level during engine operation. The control module adjusts the spark timing based on the amplitude and the frequency of the KS signal. The control module receives the KS signal through 2 isolated signal circuits. The control module learns a minimum KS noise level at idle and uses calibrated values for the rest of the RPM range. The control module should monitor a normal KS signal within the noise channel.
Knock Sensor Replacement - Bank 1
Remove the exhaust manifold lower heat shield. Refer to Exhaust Manifold Lower Heat Shield Replacement.
Disconnect the engine wiring harness electrical connector (1) from the bank 1 knock sensor (2).
Loosen the knock sensor bolt and remove the knock sensor.
Knock Sensor Replacement - Bank 2
Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
Remove the engine oil filter. Refer to Engine Oil and Oil Filter Replacement .
Lower the vehicle.
Disconnect the engine wiring harness electrical connector (2) from the bank 2 knock sensor (3).
Loosen the knock sensor bolt and remove the knock sensor.

Code p0332 low circuit knock sensor bank 2


Code means the signal from the knock sensor is lower than spec.
Could be the sensor or a problem in the wiring harness.

Have a code come up p0332 on a cadilillac 2004


P0332 DTC Code - Knock Sensor 1 Circuit Low Input (Bank 2)
A 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 #2 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0332 DTC. This P0332 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0333, and P0334.

You may notice drivability problems including fluctation engine RPM, a loss of power, and perhaps some hesitation. There may also be other symptoms.

Potential causes for a P0332 DTC include (but are not limited to):
The knock sensor is faulty and needs to be replaced
There is a wiring open/short/fault in the knock sensor circuit
The PCM/ECM has failed

Hope this helps; just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Have a nice day and thanks for using FixYa.

Service engine light on. Problem identified as P0332 Knock Sensor 2 Circut Low Input Bank 2


P0332 GM

Knock sensor circuit low voltage bank 2
- The ECM detects a KS signal voltage that is less than typical engine noise level for at least 4 seconds

Probable Cause[s]

  1. Open or short circuit condition
  2. Poor electrical connection
  3. Knock sensor
  4. ECM fault

I have a 04' Chev, 6.0L. Engine light came on, fault code came up PO332. I'm afraid the KS's are under the intake. Is there any way to test the KS to see if it is bad, or is there another problem that is...


P0332 - Knock Sensor 2 Circuit Low Input (Bank 2)

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).

Causes for P0332 DTC:
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- PCM or ECM failure.

Solutions:
- Repair or resecure the harness or connector.
- Replace the knock sensor.

Your best bet is to just replace the knock sensor for sensor 2 bank 2. Call Auto Zone with part number SU1282 this is the OEM replacement.

The knock sensor looks like this:

Diagnostic Trouble Code 332 JEEP LIBERTY ? WHAT IS THIS ?


2005 Jeep will be OBD II compliant and the trouble code(s) will be 4 digits after a P,B or U. Are you sure you wrote it down right?
For example P0332 for your car is Knock Sensor 2 Circuit Low Input (Bank 2)

Potential causes for a P0332 DTC include (but are not limited to):

  • The knock sensor is faulty and needs to be replaced
  • There is a wiring open/short/fault in the knock sensor circuit
  • The PCM/ECM has failed
Possible Solutions
  • Verify the resistance of the knock sensor (compare it to factory specs)
  • Inspect for broken/frayed wires leading to the sensor
  • Check the wiring and connections leading to/from the knock sensor and PCM/ECM
  • Verify proper voltage is reaching the knock sensor (e.g. 5 volts)
  • Verify proper grounding of sensor and circuit
  • Replace the knock sensor
  • Replace the PCM/ECM

Engine cuts out and shudders at 3000 rpm won't accelerateobd code p0332 2002 jaguar x type 3.0 l


P0332 - Knock Sensor 2 Circuit Low Input (Bank 2)

This sensor signals the engine-control computer when detonation is detected, momentarily retarding ignition timing until detonation ceases.

Most computer-controlled systems use knock sensors to ****** timing when the engine is experiencing pinging or knocking.


Obviously, a faulty knock sensor produces problems that appear to be ignition-system-related. If the knock sensor system does not provide an engine detonation signal to the PCM (powertrain control module), the engine detonates, especially on acceleration.
  • The first step in diagnosing the knock sensor and knock sensor module is to check all the wires and connections in the system for loose connections, corroded terminals, and damage.
  • With the ignition switch on, be sure that 12 volts are being supplied through the fuse to the knock sensor module.
  • A quick check of a knock sensor is to watch the ignition's timing while the engine is running and the engine block is tapped with a hammer.
    • The noise should cause a change in timing.
  • The knock sensor can also be checked by tapping near the sensor and watching for an AC pulse on a DMM or lab scope.
