I have been said by a shop that my hit sensor needs replacing. A O2 sensor is additionally bad. Organization light is top top on dashMajor question, lock told me the if mine knock sensor goes out that the vehical will stop running and also not start. True or False
Lots the money come fix.
no, yet it is something you will desire to address, obtain a second opinion.. The knock sensor is in the sink of the engine, to replace it you have to take off the entry manifold etc, it is why that $$$ to replace.
Knock Sensor
We have actually a 1998 pathfinder SE and I"ve checked out the punch sensor (P0325) come up rather a bit. By chin it won"t ever before light your inspect Engine light. I just clear the code and drive on. That is difficult/costly to change out. If you change it out you may want to consider an altering your valve sheathe gasket also (if that has to be gotten rid of or numerous items on optimal of it).I witnessed a video clip on you tube where someone reduced the wire and relocated the sensor to the height of the engine. I"m not certain how reliable that is however I guess that is absolutely an inexpensive method to addressing the problem.-dan
Replaced knock sensor
I replaced the punch sensor on mine "99 Pathy about a month ago. It in addition to a bad EGR solenoid caused the CEL come come on, and also it wouldn"t happen emissions. $750.00 later, it has actually a brand-new knock sensor, and an EGR solenoid. It will currently pass emissions. If you don"t require to adjust it, then leave it. That won"t affect performance or fuel mileage. I had actually to do it come renew mine tag, as emissions is a requirement in subway Atlanta, GA.
A bad oxygen sensor (O2 sensor) can likewise trigger the punch sensor code. I would see if replacing the faulty O2 sensor is the cause. If the engine is not acquiring the proper fuel to air mix- i beg your pardon O2 sensors requlate- they might be culprit. There are four O2 sensors in these vehicles and also most any kind of auto-parts save will confirm and also tell friend which O2 sensor(s) are involved.

Agree with above^^^if that is a prior oxygen sensor. The faulty oxygen sensor likely triggered the knock sensor code. Exactly the O2 sensor problem, erase the codes, and also then check out if the hit sensor code will reset. A bad knock sensor will not cause the engine to not start; that is supplied by the ECM to feeling engine knock for this reason the ECM have the right to in turn retard the ignition timing to aid prevent or alleviate engine damage. If the knock sensor is indeed bad, numerous use the relocation method rather 보다 pull the intake manifold. They usage a knock sensor and also subharness because that a 95 Maxima and also splice it right into the wires because that the punch sensor within the EGI harness over the appropriate side financial institution of the engine. They mount the punch sensor top top the entry manifold. It"s more than likely not as great as a ar as being straight on optimal of the engine block, yet it works. There space vids on YouTube.I should also mention there is a TSB on negative grounding at the EGI grounds on the input plenum bring about O2 sensor password on 96-00 Pathfinders. I think this is just for the behind sensors, though. Rear O2 sensors have no impact on engine performance and also are provided only to screen the catalytic converter, for this reason if the code is for the behind O2 sensor, the is most likely not the cause of the knock sensor code. The resolve for the grounding worry is installing a supplemental exploit from the EGI grounds come the next of the right financial institution cylinder head.
