HELP! Check engine light...purge volume control, idle air, knock sensor

[twistedragdoll]

I need some help or better yet suggestions...

I have had my 240 for a little over a year now. The check engine light has come on 4 times now. I've had the same 2 codes ever since - knock sensor and idle air control valve. I took my car into a Nissan dealership over the weekend. They found a new code - purge volume control. They did a fuel induction cleaning and cleaned out the throttle body and all that jazz and said that it might help and they reset the light....10 miles down the road it comes back on.

I don't have the $1100 they quoted me for parts and labor, so can anyone point me into the right direction as to where to get the parts and how to install them. I've already found the intake gaskets needed, just need the purge volume control.

just change the stuff, knock sensor is easy to change as long as u have a swivel socket, and im assuming you mean the evap purge control valve, if so its easy it right behind your pass side rear wheel, ive gotta change my idle air control valve myself tho

Changing it is not the problem, finding the part is. The dealer wants like $400 for the purge volume control and just for them to do it with parts and labor without doning the knock sensor to is like $900 - which I don't have.

Ok I now have all the parts...thanks to carquest. So the problem now is...where is the purge vol. control located and how do I change it?

TWISTED,Got a solution for you. The purge volume control valve is a pain to remove and replace. Leave the old one in and splice in one from a 96 to 98 Altima. The connectors are different. You could either chop off the connector from the engine harness and wire up the Altima connector, or keep the original harness connector and splice the old valve connector to the new valve. I recently had Code 105 keep returning after 3 cans of Seafoam(R) and various other fix attempts. The 98 Altima purge valve is easy to obtain as it sits on top of the motor. I just traced back the harness to give myself a little extra wire to work with, I took the valve, connectors, and the short bits of vacuum line. I capped the lines off and spliced in the valve. Polarity doesn't matter, so ... The connector is easy to find, but there isn't much slack in the harness to work with. This was the easiest fix I could come up with. Code's are gone. I had the IACV code, too. Now, I don't. Mileage improved.

forgot to mention, the part was 3$ at the junk yard.
