The 4.8, 5.3, 6.0 require removal of intake manifold. There is (2) two sensors in the valley that are notorious for corroding. Hope this helps.

I changed the spark plugs, amd check engine light came on. p0328, knock sensor high output bank 1 ,, i changed the knock sensor and light went off for about 25 miles and came back on


Did you change the correct knock sensor? You may have other problems that the knock sensor is detecting, which means the knock sensor is operating correctly. Knock is usually caused by detonation (cylinder firing before intended). There are many reasons this can happen. A common one, is the cylinder is running too lean.

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.

I have an 02 jeep liberty stalls after warm and is throwing multiple knock sensor codes p0325, p0330 help


P0325, P0330 are both knock sensor codes that are detected by your ECU. Considering that you are showing both codes indicates that your model trim level is either "Limited" or "Renegade" that will have a knock sensor for 2 banks (V6). Knock sensor errors will change the timing of your engine ignition and can lead to a drop in performance or worse, lead to engine stalling in order to save other components of your engine.
The common solution to remove knock sensor codes is to have the sensors replaced by an authorized mechanic; sometimes shorted electrical leads to the sensors are also a cause for the codes. Replacing the knock sensors will remove the prompting of P0325, P0330 and expect to find another fault as engine stalling is not always present with knock sensor error codes.
Hope this helps.

2000 silverado knock sensor issue


I think it not real probable that the cause of your knock sensor code is the result of bad gas. However, I suppose it IS possible. Most knock sensor codes are caused by engine mechanical problems like bad pully bearings, loose timing chains, broken valve springs, collapsed valve lifters, etc. that would cause a "knocking" or "tapping" in the engine.

The next most probable cause would be damaged knock sensor wiring. I have fixed many that have had damage from rodents getting into the engine compartment and chewing on the wires. Depending on which engine your Silverado is equipped with, the knock sensor could be mounted between the cylinder heads in the valley under the intake manifold. Mice like it under there.

Then again, it all depends on WHAT KIND of knock sensor code you are getting. For 2000 Silverado there are 3 possible knock sensor codes: P0325, P0327, P0332. The diagnostics (and possible causes) change depending on which code you have.

I have a code p0325 knock sensor 1, circuit bank 1 or single sensor problem


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 wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block.

This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0330.

Symptoms: You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.

Causes: A code P0325 most likely means one or more of the following has happened:
* The knock sensor is faulty and needs to be replaced
* There is a wiring short/fault in the knock sensor circuit

Possible Solutions
* Check the resistance of the knock sensor (compare it to factory specs)
* Check for broken/frayed wires leading to the sensor
* Replace the knock sensor


Test it and tell us news.

Diagnostic code po325 what does this mean


Hi the error code relates to the PCM Knock Sensor Circuit

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 wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. The knock sensor generally threads into the engine block. This P0325 code may show up intermittently or the Service Engine light may be lit constantly.

I failed the emisson's test. I have a 97 Nissan


P0136 indicates a bad O2 sensor. This reports poor emission performance back to the car's PCM (computer)
P0325 indicates a bad "Knock" sensor which would adversely effect drivability as far as performance is concerned. Only way to fix these 2 problems is replacement of the 2 components.
