I believe my check engine light came on because a week ago I had an overspill during fill up. It was set with the handle on the flip down with an auto shutoff but still ended with an overspill. A week later I get the code for fuel air metering, has to be the charcoal filter at the bottom of the overflow being contaminated with fuel.

I've tried resetting with the meter check out from auto zone and no luck, I still get the the check engine lite. Anyone have a solution.

Check the O2 Sensor. P1135 is Air/Fuel Sensor Heater Malfunction. When I got this code we checked the o2 sensor but it was fine. According to TRDOLMAN it can be a lot of different things however the P1135 is the Air/Fuel Sensor Heater Malfunction. Thats the code I was throwing and endd up being the Ground wire next to the Intake Manifold. But check the 1st o2 sensor thats the Air/Fuel Sensor. Go under the truck and look for the Exhaust MAnifold. From the Engine, its the 1 sensor.

What year truck/engine do you have? I doubt the charcoal cannister is the problem. A p1135 code is for the air/fuel ratio sensor bank 1 sensor 1 heater circuit. This sensor is in the exhaust system before the convertor. You probably just need to replace the a/f sensor

I've ordered a new one from urdusa, cheaper then the stealer and will install upon arrival. shouldn't take more then a few minutes of carefull wrenching.

yes sir thats the one, and with only 47K, surprised by this for sure. with this being a prerunner it's not seen any real dirt for some time, no high water either. Fuel, I've been running 87 since about 15K when I bought it, runs fine, wonder if I should up the octane a little.

2 things:
1) can someone snap a pic of this magical ground wire that comes loose on the intake manifold?
2) with that little mileage on your truck, you should see if the O2 sensor counts as emissions equipment, because i believe that has to be covered for quite a while by federal law.

Do you have a V6? The Groung wire I was talking about on the V6 is on the way for when you take out the Spark Plugs. Unless you did not lossen the wire then it should not come loose on its own. I don't know about the 4Cyl. I dont have a picture but its really easy to find. If facing the front of the truck, its just on the right side of the Intake Minifold. Maybe I am mapping it wrong, but its the sliver colored piece that the Intake Piping connects to.
