I have the SEGR installed and about 1x every 2 weeks I'll get a CEL with the Code: P0069 MAP SENSOR Calc load 32.1 ECT 165 F Map 34.2 in HG RPMs 753 Speed 0 IAT 87 F MAF lb/min 1.351 Fuel pressure 4826.8 Does anyone know what this could be? Does the SEGR interface with teh MAP sensor? Thanks for the help. |

Have you ever cleaned the map sensor? |

Try this for instructions on cleaning the sensor: http://www.lostjeeps.com/forum/phpBB3/vie ... hp?t=22630 Another member recently had their MAP sensor go bad; they bought a new one and after that, no CEL. |

Thanks for the suggestion...MAP is cleaned monthly. I am going to remove the EGR and make sure it's fully closed...the MAP was dirty after 1 month of driving with the SEGR, so my guess is that it is leaking exhaust gas alittle. I also ordered a new sensor just to be safe. |

The MAP sensor gets dirty from the EGR AND the CCV (Crank Case Vent). With the SEGR installed, the EGR is forced OFF (as in disconnected and can NEVER work, but might be cracked open a tad with some crap stuck in the seat). The dirty MAP is most likely caused by the CCV. This is where the Pro Vent comes in. Of course it's possible that the MAP is going bad too. |
