Question about 1998 Nissan Altima

1 Answer

I have a 1998 Nissan Altima. The Service Engine Light is on. I got it checked and was told that 2 codes showed up. One is for a knock sensor and the other is for a EGR Valve. How can I replace the knock sensor myself? What tools would be necessary for the replace this sensor and to clean or repair the EGR valve? Would it be much easier to have a mechanic do the job? If so how would be average labor charge for this job?

What i did is remove the check engine bulb coz even if you change the knock sensor the light will still go on coz our engine is a bit old.

I have Nissan Altima 2001 running 93500 K. since last a week service engine soon light on and showing P0141 & 0325 codes. What is the fix for P0141 and P0325 error codes.


p0325 = bank 1 sensor 2 oxygen sensor p0141 = knock sensor
if it were me you could watch the sensor on a scanner to see if working properly but without a scanner i'd replace the oxygen sensor bank 1 = passenger side
sensor 2 is sensor behind the catalictic converter screwed in

good luck

1998 nissan altima dashboard display engine service soon


Hello and thank you for using FixYa!

The service engine soon light comes on when a fault is detected in the emission system. The service engine soon light is the same thing as a check engine light. A scan tool will be needed to get the code for the failure, so the proper repairs can be made.

Thanks Jay!

I have 1998 Nissan Frontier with an engine light on. I paid a mechanic to put in a speed sensor and the light came back on the day after he put in the new part. The codes before he worked on the truck were...


the PO 325 code is for VSS vichicle speed sensor and PO500 is for a knock sensor,so you will need to see what the new code is to be able to help you, the engine power manegment is controled by both get it scanned by autozone or the mechanic that did the work and see if it's the same code, if it is you may have a short or an ecm going bad. let us know what codes you find.

Trouble code P0325 and P1444


Nissan code:
P1444 Canister Purge Volume Control Solenoid Valve

Generic OBD II code:
DTC Codes - P0300-P0399 – Ignition System or Misfire
P0325 Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor)

I hopes this helps you.
Replace or fix these two items should do the trick.

My check engine light is on on my 98 nissan 200sx


the knock sensor tells the car's on board computer/PCM that the engine is pinging/knocking from poor fuel or the wrong octane or other engine related faults, they seldom fail, most likely the connector to the sensor is making a poor connection, the knock sensor is located on the engine block, it screws into th water jacket, do u hear any engine ping or spark knock?.

Nissan xterra knock sensor


It's the valley of the engine underneath the intake manifold. It's about an $800 job because the top of the engine has to come off. However, unless you have a supercharged xterra it shouldn't effect performance. Also, the knock sensor will not trip the check engine light, as it does not indicate a primary problem, so if your light is on you should have another code that should be fixed first.

Check Engine Light


Nita0605 you should have included a little more infomation. Does the car drive any different when the light is on? Most likely you have a trouble code P0325.........Knock sensor fault or O2 sensor problem. I wouldn't worry about it until the light stays on
