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.

Where is the knock sensor located


This vehical has two knock sensors bank 1 and bank 2 ! bank 2 sensor screws into the side of the engine block closest to the firewall. and it is above the crank sensor. Knock Sensor (KS) Bank 1 sensor is on front side of engine block right of the oil filter and on the other side of knock sensor is the oil pressure sending unit.

Circuit bank 2


Knock sensors are on the side of the engine block under the intake manifold. Bank 2 would be the sensor closest to the transmission above the starter as I recall.

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:

What is PO 330 Knock 2 # 2 code is in my 99 lexus rx300 truck


P0330 = "knock sensor no.2 circuit malfunction (bank 2)." This sensor is on the bank of cylinders which contain cylinder No.2. Either the sensor is bad or the wiring to the sensor is bad. The knock sensor detects when pre-ignition (pinging or knocking) is occurring and tells the computer. The computer then retards the ignition timing to prevent engine damage.

If all connections are good "dry, tight, no corrosion" then yes. It should be a defective sensor. These sensors are piezo sensors and create a voltage when sensing a knock. A bank refers to a side on a V style engine, 2 refers to the rear sensor on your bank 2. Bank 1 should be the side with cylinder #1 which should be the cylinder closest to you on one of the sides. So your looking for the rear sensor on the opposite side.

Knock Sensor


Knock Sensors are located below the intake manifold or intake plenum and mounted to the block. They are circular and have a bolt at the center. On V6s,8s etc. and flat styled motors, they will have two knock sensors (bank 1 and 2). Bank 1 or 2 relate to V6s/8s/10s etc., or flat styled motors which have two separate heads and exhaust manifolds. Each manifold is a bank, so if there are two manifolds there are two banks. Hopefully this helps

OK, bank2 is the side where the #2 piston is on. Usually its the pasanger side. To be sure open the hood and see which cylinder head is more forward than the other. the cylinder head set back is the bank 2 side. The knock sensor is located on the bank side of the block. You dont need a special tool. only a wrench. Make sure you clear all codes after installation of sensor.
