2003 Nissan Pathfinder Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2003 Nissan Pathfinder

The Check Engine Light may illuminate due to a defective charcoal canister vent control valve. The charcoal canister is a component in the Evaporative emissions (EVAP) system.  Our technicians tell us a failed vent valve will require replacement.

The engine may not crank when the key is turned to "start" if the starter relay fails. This can be confused with a defective starter motor.

Screws inside the intake manifold can become loose causing internal engine damage if they fall out completely. Our technicians report that using a strong thread locker on the power valve butterfly screws can help prevent them from becoming loose. The manual transmission models reportedly do not have the intake manifold power valves.

Overall my pathfinder has been great. I bought it with 14k and it now has 121k, I did have to put a new exhaust on it at 80k which ive heard is very common with this year. All in all its been great only complaint is gas mileage which i wish was a little better. Id buy another one without a doubt.

I am the second owner, 75,000 miles with only normal wear, exhaust system is rusting prematurely.
