Question about 2008 Chevrolet Cobalt

My car pulled p0328 code what does that mean

The dealership replaced the knock sensor. Is that really all that needs to be done or could there be underlying issues? The car is still under warranty!

    What was the original problem? Without knowing what the original repair was supposed to correct we have no way of telling if that is all that needs to be done.

    I didn't know I had one really. Woke up this morning got in the car and the check engine light came on as soon as I started the car. It's never come on before. I took it to the dealership and my receipt shows scan PCM code p0328, inspect knock sensor and harness. Sensor open intenral. replace knock sensor. That's all I got for you other than when I hit about 40 mph the car feels like it get supercharged before it shifts down.

Thanks, that helps. It could be that is the only problem. The knock sensors started being installed several years back to provide performance feed back to the ECM/PCM. If a cylinder doesn't fire the knock sensor reports a misfire to the computer and a misfire code is shown. In this event the sensor is returning a value that indicated to the computer it was not functioning correctly. Replacement of this sensor doesn't require the motor to be rebuilt should cost around $200 at a dealer maybe a little more. You can view the knock sensor a little like the O2 sensor with the main difference being that if the knock sensor doesn't work correctly it could cause the vehicle to computer to adjust your timing the wrong way.

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.

How do i deal with Error Code P0328


the following information courtesy of OBD-CODES.com P0328 Knock Sensor Circuit High Input OBD-II Trouble Code Technical Description Knock Sensor 1 Circuit High Input (Bank 1 or Single Sensor) What does that mean? 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 retard the spark timing to avoid pre-detonation. Most PCMs have the ability to learn spark knock trends in the engine during normal operation. A P0328 code is a generic DTC, thus it applies to all makes of vehicles, and refers to a high output voltage of the knock sensor. In many cases, this means the voltage is above 4.5V but that specific value depends on the specific make and model of vehicle. This code refers to the sensor on bank #1. Symptoms Symptoms of a P0328 DTC may include: MIL (Malfunction Indicator Lamp) illumination Audible knocking from the engine compartment Pinging from engine under acceleration Loss of power Irregular RPM Causes Potential causes of a P0328 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 Loose knock sensor Electrical interference in circuit Low fuel pressure Incorrect fuel octane Mechanical engine problem Failed/faulty PCM Possible Solutions If you can hear engine knock (detonation), first fix the source of the mechanical problem and retest. Ensure the correct octane fuel was used (some engines require premium fuel, check the owners manual). Aside from that, for this code, most likely the problem will lie either with the knock sensor itself or the wiring & connectors going from the sensor to the PCM. Realisitcally, for the DIY vehicle owner, the best next steps are to measure the resistance between the two knock sensor wire terminals where they go into the PCM. Also, check the voltage of the same terminals. Compare those numbers to the manufacturer's specifications. Also, check all wiring and connectors leading from the knock sensor back to the PCM. In addition, you should also check the resistance using a Digital Volt Ohm Meter (DVOM) of the knock sensor itself, compare it to the vehicle manufacturers specification. If the knock sensor resistance value is out of spec, then it needs to be replaced. Other knock sensor DTCs include P0324, P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0332, P0334 Register now to ask a question (free) Related P0328 DTC Discussions

P0328, P0462


Code 328 is for the knock sensor which is a common code for Nissan products. it does not always mean the sensor has failed.
Code 462 usually means the computer is not getting a signal from the sending unit in the gas tank. Have you checked the signal at the tank harness ?

Knock out sensor


unless your xterra is supercharged, you really do not need to replace it. its a lot of work, because its located way down under the upper plenum and lower intake. its way down there. if it is supercharged, you do need to replace it, because it puts the supercharger into fail safe mode and truck till not run to its full potencial.

I have a 2003 chevy siverado 2500 hd and knock sensor code is on but truck runs smooth what should i check before taking it to dealership


Hi, the knock sensor helps the computer optimize ignition timing and yet avoid detonation. When the sensor fails, the computer defaults to a timing that is less fuel efficient. Replacing a knock sensor is usually easy, provided there is access under the engine. Depending on which engine you have, it's usually centered on the block just below the cylinder head. There is one sensor on each side, and the trouble code should have indicated bank 1 (driver's side) or bank 2 (passenger's side).
Please let me know if you have more questions, and thanks for using FixYa.
