on my gmc i have 2 knock sensors and im not possitive if you have two or not under your intake mani but when i replaced both mine i got the same code of low input so i took the small needle out and wire brushed it clean and also traced and ran a new wire just to be safe and that solved my problem. as for bank 1,2 if it helps any my bank one is located engine side driverside and bank2 is engine side passenger side and 3 and 4 are underneath bed side. but you can see the sensors if you look real close near the headers. hope this helps

I recently changed both knock sensors and wiring harness on my 99 Lexus rx 300! I purchased the parts on ebay and they state (OEM PARTS) Check engine, P0330,


code p 0330 refers to knock sensor (KS)2 bank 2 ---circuit malfunction===causes wiring--KS---ECM
it is possible that in changing the harness there is a problem connection or the connection to ks2 is not correct ( not on properly)

2000 Nissan frontier ran rough and stalled out. will not start. only code is for knock sensor. Could the knock sensor cause this?


Ecu collects data from all sensors. If they don't "add up" it throws the code. Could be corrosion on the connection or connector is off.
Find the knock sensor on the block, check the connection. If a bad connection scrape spade to bright metal both sides reconnect, clear code. Recheck codes. No help must be knock sensor. so must be changed.

2003 Escalade 6.0L AWD p0327 code replaced both knock sensors and harness. Cleared codes 10 miles later light came back on p0327. What do i look for now?


  • 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

I have a 99 chevy 1500 4x4 5.3 l got code po 332 put new ones in same code saws low voilts


This condition may be the result of corrosion of the rear bank knock sensor due to water intrusion into the sensor cavity. This condition is more apparent on vehicles in which customers frequently wash the engine compartment. Replace the rear bank knock sensor and build a dam (wall) around the sensor using RTV to divert water away from the sensor. Also, check for corrosion on the connector plug. Visually inspect the wiring going to the Rear Bank Knock Sensor for damage. After you have replaced the sensor, and checked for damages, have the code reset and see if it comes back.

Getting codes P0325 and P0420. Where to start?


Hi,

code P0325 is for knock sensor and it looks like is a common problem with these engines.You might need to replace the knock sensor, and this is a few hours job for a qualified mechanic.You can try first using a high grade gasoline, but I doubt it will fix the problem.
code P0420 -right bank -B1 three way catalyst function.
possible cause for P0420:
-you might have a hole in the exhaust tube
- you might have some intake air leaks
- injectors leaks
-spark plugs
check first for some damage exhaust tube.or it might be related to code p0325, as a change in timing dictated by knock sensor malfunction.
hope this will help.
Good luck.

I have an engine code PO332 knock sensor 2 circuit low imput bank 2 what is this problem .the car is a 2001 gmc yukon xl .


The most likely cause of your code is a bad rear knock sensor. You should check the knock sensor wiring harness for corrosion. But if that checks out the sensor will have to be replaced. The knock sensor is under the intake manifold, although it's not too difficult to remove. Both knock sensors should be replaced along with the wiring harness, just because of labor involved in gaining access to the sensors. You could try clearing the code, it may stay off for a long time.

Service engine light


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.
