    Hi Teahou thanks for your reply, they stated the code p0185 and listed the part as the turbo boost sensor put foot to floor of accelerator and it blows really bad black smoke when driving it makes a sucking sound tho its sucking in air the revs keep going up and a distinct lack of power its a jeep chrokee crd 2.8 cheers

    po185 is a fault code, not a part. My only code book on that car dosen't list it...but it sounds like a possible fuel pressure regulator problem. Regulator is on the top of the fuel pump. Do not replace it though 'till you verify that there is a pressure problem (with gauge)

    OK. Let me know what the new code is when you get it checked.

  • teahou May 11, 2010

    black smoke indicates a very rich condition (way too much gas). Common cause is the coolant temp sensor for the computer. You would get a code P0185, which is an O2 sensor code, because the oxygen sensors would be damaged by the excess fuel but they wouldn't cause the excess fuel condition.
    Take it to a parts store that offers free code retrieval and let me know what the code is.

Lost power smoke exhaust

If it is a 6 cylinder inline then catalyst is plugging up a easy test would be to remove a oxygen sensor and see if power returns to normal. V-8 models have 2 types of manifolds plastic and metal the metal ones have a plate bolted to the bottom which the gasket splits and sucks in engine oil causing all sorts of drive ability issues the plastic versions more trouble free but PCV ventilation system can cause smoking

I have a 1997 Jeep Grand Cherokee 2.5 diesel. Starts, idles and drives along motorway all fine. But when I slow down and change to lower gears/revs, to go through town, etc, get black smoke from exhaust...

Soungs like egr valve is stuck open. Take it off and look inside small hole on the bottom. The pintle inside should be all the way closed. If not then replace the egr.

Jeep Grand Cherokee Power Loss

a bad cam sensor will cause vehicle to shut off while driving, and cause a hard time starting. but this usually sets a trouble code p0340. scan vehicle to see if any codes come up. after it is fixed, erase codes with a obd2 scanner. if you do not have one, you can go to any auto parts store and they will erase codes for free.

Renault megane diesel black smoke

This could be as simple as the EGR (exhaust gas recycling) valve stuck open. This valve is supposed to open at a specific time, recycling the exhaust gasses back through the engine. If they stick open, the engine is not getting the correct air mixture to burn the fuel efficently, causing black smoke and lack of power. Have the garage remove and blank off this valve. If it runs ok, then a new EGR is needed.
