Some codes my Pathfinder is throwing


Recommended Posts

I took my Pathy into Autozone for a diagnostic and I got the codes:


P0442: evap control system- small leak detected, P0171: Fuel system lean bank 1, and P1490: vacuum cut valve bypass valve (circuit)


Anything I should be deathly afraid of and have it serviced ASAP? :)


Thanks in advance guys.

In the FSM EC-267 starts the procedure for your P1490 Vacuum Cut Valve Diagnostics. Looks pretty easy to do. Baring where the sensor is located and actually getting to it.

The P0442 is probably directly related to that code. I would figure out the P1490 and see if once you fix that and clear codes. That it stays away.

For your lean condition, start in EC-273. Simple things to check are intake leaks etc. But, could also be correlated to your Vacuum issue.
