| Post subject: | Water in fuel light, oil light, fuel light, fuel gauge on E? |
Went out and started up the Jeep the other day and all these lights came on immediately. Fearing the worst, I quickly looked underneath to see if there was a large puddle of oil, nope nothing. I then popped the hood and the oil level was perfect. Only have 190 miles on this tank of fuel so no reason for fuel gauge on E or low fuel warning. Plus I had just driven it 30 miles to where it was parked at the time. The fuel head/filter was brand new in March and had no water in it. I drove it the last 2 miles home and the AC didn't work and the electric pusher fan ran constantly. Scanned the computer for codes at home with the Torque Pro app only to get "AC system pressure low". It blasted ice cold just before all this happened. Tried the gauge cluster self test and every gauge swept normal, all lights illuminated as they should. I Googled and searched the forums only to find a few threads with similar symptoms but none with solutions. Most recommended checking the Front Control Module connections, mine turned out clean, no chaffed wires, and zero debris or corrosion. Cleaned and added additional ground strap anyway. Battery is brand new as of last October, put the maintainer on it anyway. Zero corrosion. **Cut to the chase** Checked tons of stuff, everything checks out good, what is next? Anyone else encounter this problem? |

I left the battery out of it for a couple days to try and "reset" the computer. No luck there at all. Took her for a 10-15 min test flight to see if anything changes while moving. The gas gauge will occasionally come up off of E momentarily shut off the low fuel light, then return to zero, ding and turn the low fuel light back on. The Jeep drives perfectly normal, or just as normal as it did before. It has full power, full speed, no excessive smoke and runs smooth and quiet. There has to be some common junction where the signals come together that has crapped out. Does anyone have any schematics? |

I bet its related to your oil warning light issue a few weeks ago. Seems like it would be a gauge cluster connection. Did you check anything under the dash? This might not be related, but I remember a guy who had a cruise control issue, turned out to be the radio. Just saying, weird things happen. |

What was the resolution to this? I'm having nearly identical problems. |

If you are having this problem check this thread as well viewtopic.php?f=5&t=80457&start=0 My issue turned out to oil pressure sensor, but could be any of those listed in the attached thread. |

Excellent. Thanks! I'll work on it next weekend and post the results. |

I never updated. It was the Gateway module (front control module). Apparently, several sensors share a common ground in that module and if the module goes bad all those sensors get wonky. |

UPDATE! I have found the culprit! After reading this fantastic forum I have solved my issue! It was the oil pressure sensor. After reading through many threads I saw someone posted about checking each sensor that had a warning light associated with this problem. I then recalled the a long time before I had my issue that I had replaced my oil pressure sensor because the oil light would flicker on and off at random. I got under the Jeep the other day, unplugged the oil sensor, and BOOM! No more lights all over the dash! (except the oil light of course) My fuel gauge works, water in fuel light is off, and my intermittent AC is corrected! I didn't realize the AC issue was associated with all this other stuff. |
