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

2004 nissan xterra run great for 12 miles then misfiring,cnt get over 45 miles an hour. codes p 0733,p0420,p0430,p0328 comes up. new wires,new cap,rotor spark plugs 6 months old timming belt 6 months...


code p0733 refers to gear 3 -incorrect ration===causes---wiring---TR sensor/switch--shift solenoids---transmission mechanical fault
code p0420 refers to catalytic converter system -bank 1---efficiency below threshold===causes--cat converter--wiring--HO2s 2
code po430 refers to cat converter system bank 2--efficiency below threshold===causes--cat converter--wiring ---HO2s 2
code p0328 refers to knock sensor (KS) 1 bank 1--high input===causes--wiring short to positive--KS incorrectly tightened--KS---ECM

basically replace the cat converters as they are blocking the exhaust system and preventing your over 45mph problem
replace the TR sensor/ switch as you have not mentioned a transmission problem
Rectify the problem with the KS as it controls the air/fuel mixture setting which contributes to the car getting hot.

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 ?

I have a 2002 Nissan frontier SC, 69000 miles. Motor runs well when first start the engine and runs very routh after warm up and it just stops sudenly the engine. Three codes P0328(knock sensor 1 circ


P0328 Is knock sensor code,all Nissan have this code so leave,concentrate on P0101 and P0103 this is MAF(mass airflow),Just make sure the timing belt is in good condition and the marks are correct, your solution is NTB02-003A In other word you need a reprogram on the ECM

A new knock sensor was installed, new air filter, new hose-old was leaking antifreeze. The engine light went off but came back on 30 to 40 minutes later. The computer was reset on two different...


Ok.. the p0328 is in fact a bad knock sensor. I would suggest that someone replaced it incorrectly or the wrong one.. maybe even the wrong part.

p0442 is a small leak in some part of the evap system. Faulty gas cap can cause this but if it was not there before I would suggest the shop knocked something loose or cracked a hose during their repair.

p0456 is a large leak in the same evap system. Likely related to the p0442.

Good luck.
