P1131 code ford f150

I have ford f 4. Had a new fuel pump the whole assembly … original equipment not aftermarket installed about 3 months ago mid-June and changed the fuel filter as well. Mostly I drive it p1131 code ford f150 once per week … just long enough to get everything warmed up at least 20 minutes or so.

P error code. Thread Tools. Hey guys I'm getting the p error on my xlt f 5. I know it's usually a vacuum leak on the pcv hosing, which I did have at the back and replaced as well as other softer joining sections 3 to be exact lol , but I'm still getting this error. Since this is an obvious indication of a lean burning cylinder can I make the assumption my most likely problem is dirty fuel injectors on those cylinders? Yeah yeah I know I'd clean them all lol.

P at startup. Thread Tools. Likes: Received 9 Likes on 8 Posts. P during warmup. My '99 4. Code P is upstream bank 1 oxygen sensor too lean. The code will persist for a few weeks, then it will go away for a few weeks. Change in state seems to coincide with filling the tank with gas. I replaced the gas cap and am careful to fully seat it. Engine runs fine: no issues starting, smooth idle, MPG. The CEL comes on 5 minutes after I start the engine. P is the only code. If I clear the code.

This is not hardware but software.

The error code P is displayed by getting feedback from the Lambda or the oxygen sensor. The Lambda sensor is responsible for detecting the amount of oxygen in the exhaust gases. Based on that, the PCM Powertrain Control Module manipulates whether the engine is running on a lean or rich fuel mixture. A lean running condition of the engine happens when the engine runs on less fuel or too much air , ultimately resulting in the error code P on Ford vehicles. An engine running on a lean mixture, may lead to sluggish acceleration and reduced fuel economy.

While this may seem harmless at first, keep it hanging for long enough, leading to part damages and decreased fuel economy. The P Ford code is linked to the oxygen sensor and signals the engine is running on a lean or rich fuel mixture. This article will discuss everything about the P Ford code, from what it means to diagnosis and fixes. Error Code P is displayed when sensor 1 or the oxygen sensor bank 1 does not switch enough to lean. The heated oxygen sensor voltage is below 0. Any Error Code that begins with P1xxx is a manufacturer-specific diagnostic trouble code. In short, a P Ford code indicates an issue with the O2 sensor in a Ford vehicle.

Had a new fuel pump the whole assembly … original equipment not aftermarket installed about 3 months ago mid-June and changed the fuel filter as well. Thermostat too cold or stuck partially open causing the same condition as D. Engine runs fine: no issues starting, smooth idle, MPG. The Ox sensor is no longer able to 'switch' when the table is so far out of limits. Last edited by BigEd54; at PM. P during warmup. Leaking injector. Well you took exception to my help. You see both an air leak and an excess in fuel can cause the same end result. Change in state seems to coincide with filling the tank with gas. Since I have one it is cheap for me.

For the code you could have one or more of the following; an air leak, short to power in the harness, water in the connector, corrosion in terminals, excessive fuel pressure, low fuel pressure, and a bunch of other possibilities that affect the fuel or air.
