Question about 2001 Toyota Sienna

2 Answers

Knock sensor code, p0330


Knock sensor codes were read on obd, what are the chances that knock sensor(s) need to be replaced? or could the wiring just need to replaced or adjusted....or could something else be contributing to cause these codes to go off. Also, if knock sensors need replacing, how much should I expect to be paying?

The knock sensors either work or they don't. When they do not, the light comes on. All that a knock senor is is a piezo crystal that vibrates at the frequency that is comparable to engine "knock", and sends that yes/no signal to the ECU. There are 2 knock sensors, and both are bolted to each side of the engine interior walls, under each cylinder head. You have to remove both of the intake manifolds to access the knock sensors and their wiring.
Price to pay? My flat rate book suggests 3.7 hrs to change both. 3.7 hrs times your local labour rate, plus the price of the 2 sensors and/or wiring, and the price for the gaskets for the upper & lower manifolds. Depending on your location, you could quickly spend over $500.00.

When one of our Knock Sensors failed, it did NOT fail completely. Testing it on an ocsilloscope, however, showed that the microphonic pickup ouput was not normal compared to the new ones. So some fail but do not show to be bad with a simple DC check. Worth considering. Once changed - all codes disappeared of course. Quite an involved job but not rocket science.

We made a page to show the procedure with pictures etc.

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

WHAT ARE CODES PO330 AND PO320 CTS 2006 CADILAC


I use this website all the time:
https://www.obd-codes.com/p0320
https://www.obd-codes.com/p0330
https://www.obd-codes.com/p0420
https://www.obd-codes.com/p0430

Now the art is knowing how to interpret, the P0320 and P0330 can set off your P0420 and P0430 oxygen sensor codes. I would address the P0320 and P0330 first and probably the O2 sensor stuff will probably go away. If your car is knocking, rough idle, loses power, etc. then the 300 codes make sense and you have issues. It could also be two separate issues were damaged wiring on the knock sensors and then a damaged catalytic converter. I've got a car that constantly throws up 420 and 430 codes because the catalytic converter got dinged up from running something other.

The codes read p0330 and it was running until they diagnosed it now it's sitting in auto zone parking lot won't run at all


This code usually refers to a ignition control / knock sensor. What kind of vehicle is this, year, model?

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.

Code p0330 knock sensor does this affect the way it shifts if engine light is on


Possible but unlikely. Code p0330 refers to knock sensor(KS) 2 bank 2-circuit malfunction==causes --wiring --KS--ECM. Replace the KS. The engine light is telling you that there is a problem with sensors in the ECM and that is what will be affecting the performance . Shifting is the area of the TCM( transmission control module ) so have that checked out as well

Cheking engine light is coming code p0330


this obd2 trouble code table can help you understand the meaning of code, for this code, you can try:
Check the resistance of the knock sensor on bank 2 (compare it to factory specs)
Check for broken/frayed wires leading to the sensor
Replace the knock sensor on bank 2

GMC 4.3L DTC P0330 flashing MIL


P0330 - Knock Sensor 2 Circuit Malfunction (Bank 2)
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 P0330 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325.

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

Causes: A code P0330 most likely means one or more of the following has happened:
The "B" 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 on bank 2 (compare it to factory specs)
Check for broken/frayed wires leading to the sensor
Replace the knock sensor on bank 2


Hope helps.

It does sound like the sensor may be bad, but you also need to check the wiring.
