I would go with oxygen sensor, but I don't have a service disk, hopefully someone here does |

EGR is different to o2 sensors & the code relates to EGR's as posted i'd say the EGR valve/pipe is carbon-ed up, not sure what the set up is on the jimny's though. EDIT: looks like from this thread you've got a m18a jammed in there... could be a number of things, maybe it has been over fueling & pumped a heap of carbon through the EGR. viewtopic.php?t=41121 |

Usually the ECU will test exhaust flow during deceleration by turning on the EGR briefly and measuring the rise in manifold pressure. A lack of flow could be due to blocked passageways or insufficient back pressure. |

what have you done for an exhaust manifold when you did the m18 conversion ? |

I used the exsisting m13a exhaust system |
