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.

2006 Chevy cobalt just did a tune up and now have these codes on my car P0326,P0300,P1516,P0496,P0128,P0411.


Hi Heather , so who did the tune up ? By all these codes it mustn't run very well. What engine does yours have 2.0 l- 2.2 l - 2.4 l ?

P0128 coolant sensor An engine coolant temperature (ECT) sensor monitors the temperature of the coolant. This input is used by the powertrain control module (PCM) for engine control and as an enabling criteria for some diagnostics.
P0326 knock sensor
The knock sensor (KS) system enables the powertrain control module (PCM) to control the ignition timing for the best possible performance while protecting the engine from potentially damaging levels of detonation. The KS is located on the intake side of the engine block. The KS produces an AC voltage signal that varies depending on the vibration level during engine operation. The PCM adjusts the spark timing based on the amplitude and the frequency of the KS signal. The PCM receives the KS signal through a signal circuit. The KS ground is supplied by the PCM through a low reference circuit. The PCM learns a minimum KS noise level at idle and uses calibrated values for the rest of the RPM range. The PCM should monitor a normal KS signal within the noise channel. When the PCM detects a KS signal that varies outside of the noise channel, the PCM will retard the spark timing until the knock goes away. If the PCM is operating on large amounts of spark retard and is unable to eliminate the knock, DTC P0326 will set.
DTC P0411 : Secondary Air Injection (AIR) System Incorrect Air Flow Detected
P0496 This DTC tests for undesired intake manifold vacuum flow to the evaporative emission (EVAP) system. The control module seals the EVAP system by commanding the EVAP canister purge solenoid valve OFF and the EVAP canister vent solenoid valve ON. The control module monitors the fuel tank pressure (FTP) sensor to determine if a vacuum is being drawn on the EVAP system. If vacuum in the EVAP system is more than a predetermined value within a predetermined time, this DTC sets.
P1516 The commanded throttle position is compared to the actual throttle position based on accelerator pedal position (APP) and possibly other limiting factors. Both values should be within a calibrated range of each other. The engine control module (ECM) continuously monitors the commanded and actual throttle positions. This DTC sets if the values are greater than the calibrated range.
P0300 The engine control module (ECM) uses information from the crankshaft position (CKP) sensor and the ignition control (IC) module to determine when an engine misfire is occurring. By monitoring variations in the crankshaft rotation speed for each cylinder, the ECM is able to detect individual misfire events. A misfire rate that is high enough can cause the 3-way catalytic converter (TWC) to overheat under certain driving conditions. The malfunction indicator lamp (MIL) will flash ON and OFF when the conditions for TWC overheating are present. If the ECM detects a misfire rate sufficient to cause emission levels to exceed mandated standards, DTC P0300 will set.
Did you all have a lot of stuff disconnected ? What all got replaced ? What would like to know ?

I need to know what code p0326 means for a 2001 kia sportage. i know it a knock sensor code what do i do with information.


Knock sensor is an indication you are having a mis-fire with your spark plugs if one fires and another misses causes the engine to knock 3 possible issues.

Spark plugs

Older vehicle may need gas treatment

Worst case valve or cylinder seal issue
Try the first issues dont change knock sensor it maybe doing its job

The last solution you shouldnt need to do unless you are getting black smoke from exhaust or engine is knocking realy bad

Emission code P0326


P0326 - Knock Sensor 1 Circuit Range/Performance (Bank 1 or Single Sensor) High Voltage
Knock sensors are used to detect engine pre-detonation (engine knock or ping). The knock sensor (KS) is usually a two wire sensor. A 5 volt reference is supplied to the sensor and there is a signal return from the knock sensor to the PCM (powertrain control module). The sensor signal wire informs the PCM when a knock occurs and in what degree of severity. The PCM will ****** the spark timing to avoid pre-detonation. Most PCMs have the ability to learn spark knock trends in the engine during normal operation.

If the PCM determines that the knock is out of the ordinary or that the noise level is abnormally high, P0326 may set. If the PCM senses that the knock is severe and cannot be eliminated by retarding the spark timing, P0326 may set. Keep in mind that knock sensors cannot distinguish between a knock from pre-detonation or one from engine problems.

Symptoms of a P0326 DTC may include:
MIL (Malfunction Indicator Lamp) illumination
Audible knocking from the engine compartment
Pinging from engine under acceleration

Potential causes of a P0326 code include:
Knock sensor connector is damaged
Knock sensor circuit is open or shorted to ground
Knock sensor circuit is shorted to voltage
Knock sensor has failed
Moisture in knock sensor connectors
Incorrect fuel octane
PCM has failed

Possible Solutions:
If an engine knock can be heard, fix the source of the mechanical problem first then retest. Make sure the proper octane of fuel was used in the engine. Using lower octane fuel than what is specified can cause a ping or pre-detonation and may cause P0326.

Unplug the knock sensor and check for water or corrosion in the connector. If the knock sensor has a seal, verify there is no coolant from the engine block fouling the sensor. Repair as necessary.

Turn ignition to run position with engine off. Ensure that 5 Volts are present at the KS connector. If there is, check for proper resistance between KS terminal and engine ground. You will need a vehicle specification for this. If resistance is out of specification, replace the knock sensor. If resistance is normal, plug KS back in and idle the engine. Using a scan tool in datastream, observe KS value. Does it indicate a knock is present at idle? If so, replace the knock sensor. If the knock sensor shows no knock at idle, then tap on the engine block while observing the knock signal. If it doesn't show a signal that corresponds with the taps, replace the knock sensor. If it does, verify the knock sensor wiring isn't routed next to ignition wires. If there was no 5 volts present at the knock sensor connector while unplugged with KOEO (Key on engine off) then go back to the PCM connector. Turn ignition off and clip the knock sensor 5 volt reference wire in a location that is easy to repair (Or remove the wire from the PCM connector). With KOEO, check for 5 volts on the PCM side of the clipped wire. If 5 volts isn't present, suspect a bad PCM. If 5 volts IS present, repair short in 5 volt reference circuit.

Since the reference circuit is a shared circuit, you will need to check all engine sensors that are fed a 5 volt reference. Unplug each sensor one at a time until the reference voltage returns. When it returns the last sensor you plugged in is the shorted sensor. If no sensors are shorted, check the wiring harness for short to voltage on reference circuit.

Hope this helps; also 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.

Thank you for using FixYa, have a nice day.

Where can i find knock sensor on elantra 2009 2.0 litre engine and how to test it?


Here's a pic of its connector's location -- follow the harness and you'll find this sensor on the right hand side of the cylinder block below the intake manifold (14mm bolt attaches it to the block).

This sensor can only be checked, not tested. If you have a DTC set (i.e. P0326 Knock Sensor 1 Circuit Range/Performance (Bank 1 or Single Sensor) the diagnostic performed by the engine computer is better than any bench test you could perform without an oscilliscope. It has a resistance you could check, but it wouldn't be revealing/absolute.

Your not going to here any knock from the engine the knock sensor detects detonation which is not detectable with the human ear. if you want to test the knock sensor you can tap the side of the block the engine should stumble for a couple of seconds if it does not change then the way the engine runs then the knock sensor is defective or hase buildup iside the engine and you will need to do a top engine clean. if you want instructions on how to do this just post another post to this reply This happens on engines that ave high mileage or acar that runs low grade like regular.
