Car Forum / Nissan / Nissan Cars / March 2006Water in fuel = SES Light on
So I finally went to Auto Zone and had them read my error code and turn off the light. Code was 1140. Water in fuel system. I drove a few miles, stopped and went into a store and when I came back out and started the engine the damned light came back on. So what's the best thing to pour into my tank to eliminate water?

[quoted text clipped - 7 lines] > > You might want to tell us what you're driving... Indeed I might. 2001 Pathfinder SE that had 45,700 on it when I bought it. Had 47 or 48k when the light came on the first time. It has just over 50k on it now. vq35de engine. 240 hp with the auto tranny. 2wd SignatureTFM® My 2001 Pathfinder manual disagrees with Auto Zone: I can't find any code for water in the gas. For code 1140, it says: DTC P1140 (RIGHT, -B1), P1145 (LEFT, -B2) INTAKE VALVE TIMING CONTROL POSITION SENSOR (CIRCUIT) There's a static resistance and voltage check in the service manual. I'd do that, then swap the two sensors (left and right), and get the code cleared. It will probably come right back, but as P1145 this time, in which case get a new sensor and replace the bad one (now on the left). >>> So I finally went to Auto Zone and had them read my error code and turn off the light. >>> [quoted text clipped - 13 lines] > > 2wd >So I finally went to Auto Zone and had them read my error code and turn >off the light.

Water is heavier than gasoline and will settle to the lowest point where it can be easily drained off. Happens all the time to aircraft that have just been washed or rained on. > So I finally went to Auto Zone and had them read my error code and turn > off the light.

A bottle of methylated spirits dissolved the water nicely. Promptly followed by replacing the perished filler-cap seal. you may want to take it to a shop that knows diagnose a problem and not some minimum wage ham and egger at Auto Zone first thing, Nissan does not have or use a code for water in the fuel. if my memory is correct, P1140 has to do with one of the intake cam timing sensors. > So I finally went to Auto Zone and had them read my error code and turn > off the light.

In his defense, that's what the Auto Zone computer told him. So how big a job is replacing the intake cam sensors? SignatureTFM® No big deal. They are pretty accessible on the front of the head. IIRC, you need to pull part of the air duct. I pulled mine, ran some DC tests on it, and had it back in about an hour. >> you may want to take it to a shop that knows diagnose a problem and not some >> minimum wage ham and egger at Auto Zone [quoted text clipped - 7 lines] > > So how big a job is replacing the intake cam sensors?
