1999 Nissan Maxima SE from North America - Comments

Dear friends,

I have all the same problems you have, but I just found this website that is very useful, here it is...

http://www.motorvate.ca/mvp.php/507

My '99 Maxi came up with these following codes:

P0400 - EGR SYSTEM PROBLEM

P0325 - KNOCK SENSOR PROBLEM

P0139 - H02S2 SLOW RESPONSE

P0138 - H02S2 RICH SHIFT.

Where should I start?

I have a 97 SE 5 speed with a locking diff.

I have have the engine light on since I bought the car, 40,000 ago.

When I used the Checkers code tester, it reported a knock sensor and air temperature sensor.

I have a cold air intake, again I bought it this way. and the air temp sensor is not even hooked up.

The knock sensor is a common item to break; splits in the body of the sensor.

There are several sites that show how to replace the knock sensor in 30 to 45 minutes. I paid $61 dollars for the sensor from Checkers. Without fixing or replacing anything, I have past emissions twice here in Denver.

I have found the Maxima very easy to work on. I have done the shocks, brakes, tire, and replaced both half shafts.

This is one of, if not the best engines Nissan has ever built (95-99). The locking diff is great in the snow. I have never used anything but 91 octane fuel!

This is not a car for a kid. I am not sure what the HP is on my car as there are a few mods on it with a cold air intake and over sized exhaust for two, but I can get 30 MPG if I drive sensible, and be at 80 MPH in third gear getting on the freeway in a VERY short time.

I had a 92, another great car, and my wife drives a 98 GLE Maxima. As several people have stated, research everything online, and shop for prices on parts. PS specialized tools are free for the use at Checkers, just ask.
