My car Isn't showing a check engine light, but when I hook up my OBD-II Scanner it shows P0333 Knock Sensor 2 Circuit High Input (Bank 2).
My Scanner says Ignition System Misfire
Freeze Frame

Fuel System - Closed Loop
Calculated Load - 41%
Coolant Temp - 163f
Short Term FT B1 - 16.38%
Long Term FT B1 - -0.78%
Engine RPM - 3400
Vehicle Speed - 50 MPH

Also one of my O2 sensors is running rich at 96.06% and the performance is down on the car. Does anyone know what this means?
Thanks , Kevin

 

I would replace the O2 snesor and Clear the Knock sensor code and see what happens.

If it is running to rich and pinging because of the O2 sensor it will throw the knock sensor code.

 

Thanks Tech, I'll try that and see what happens, although I don't know which one it is!

 

It doesn't show front or Rear?

 

Hey Tech, all it shows is this,

B1 S2 O2 Sensor Output Voltage .430
B1 S2 O2 Sensor Fuel Trim 99.06%
B1 S1 Wide Band O2 Sensor 2 Equivalence Ratio .999 LAM
B1 S1 Wide Band O2 Sensor 2 Voltage(anywhere from) 2.014-5.013

 

B1 S2 O2 Sensor Output Voltage .430
B1 S2 O2 Sensor Fuel Trim 99.06%
That should be Bank 1 sensor 2 by the first 4 things B1 should be Bank 1 S2 should be Sensor 2 (Rear)

B1 S1 Wide Band O2 Sensor 2 Equivalence Ratio .999 LAM
B1 S1 Wide Band O2 Sensor 2 Voltage(anywhere from) 2.014-5.013
That should be the Front sensor.

The rear one only monitors the front one. But if the Rear goes bad it will mess up the system.

 

Thanks Tech, Think I should replace the one or both?

 

If you can afford it I would do both to be safe.
This way the other one doesn't crap out after you replace one.

 

Thanks alot Tech! Hopefully I'll order one or both in the morning, Bosch OK?

 

Bosch is the OEM ones. Thats good.

 

KC!

Did you ever solve your problem?

I'd like to know.

 

Sorry, I haven't been on here in awhile. Volvo 2001, no the problem didn't get fixed. I replaced both O2 sensors and that code still comes up along with the P0422 Main Cat. Eff. I don't know what else to do, I don't want to take it to a dealer because they'll probably sell me stuff that wont fix it. Kevin

 

If you keep coming up with a Cat. Effic. code I will bet the injectors are bad.

 

Thanks Tech, do you know what lb/hr the injectors are? I remember that I put Ford Racing injectors in my Camaro because they were alot cheaper from Summit Racing and are made by Bosch, they worked perfectly. Do you think that's what could be causing my P0333 Knock Sensor code as well? Thanks for any comments, Kevin

 

Not exactly sure if it would cause the knock sensor code as well but it might be.

I will have top see If I can find out any info on them but really haven't been able to find any as of yet.

I have found this online but I belive the S60 are Yellow and it isn't on there.
