    Default 04 Signum 2.0 DTi giving P0105 and P1105

    My '04 Signum 2.0 DTi keeps giving me error codes P0105 and P1105 and the car is in 'limp' mode. It only used to happen occasionally, but last night I drove a few colleagues to a works do (about 25 miles) without any problem on the way, but on the way back the car went into 'limp' mode about 10-15 times on the way back. Switching the ignition off and then on cures it for a bit, but then it comes back.

    Today, I drove the car and it only happened twice in the 20 miles I drove. I checked on line and people are saying that it could be a faulty MAP sensor. Where is this sensor and is this the most probable cause.

    It seems like it goes wrong more when the outside air temperature is cold.

    Any help is much appreciated.

    boost sensor is on the top part of the inlet manifold , at the engine side & is held in with 1 torx bolt .
    my vectra dti did the same thing when I first bought it & limited itself to 3000 rpm , cleaned the boost sensor & wiring plug , all ok after that .

    p0105 & p1105 are related to your barometric pressure sensor , this sits behind your maf in the engine bay. first thing to do is to clean and check the elec connections between the sensor and the maf , at the same time remove the sensor and clean the sensor port with carburretor cleaner , this may be all thats needed but these sensors do fail eventually

    P0105 & p1105 are related to your barometric pressure sensor ,
    p0105 is your ecu telling you it has detected a fault with the sensor
    p1105 is your alternator saying it has detected a high value fault which usually means a open circuit or a short
    First thing give the sensor port a clean with some carburrretor cleaner by removing it the port is at the bottom
    Next give the elec connections a clean with some emery paper or wire wool .
    Replace and see what happens it may solve it but failing that then its probably a new sensor thats required .

    Havn't got round to looking at the MAP sensor, had to finish my extension, give birth to my first child (well, the misses did) and general other stuff. But I have found if the outside air temp is above 10 degrees, the fault very rarely occurs. I've got a space 5 minutes tomorrow, so I'll take the sensor out and clean it. Then I'll wait for a cold day, should be one soon, and see if the problem is solved

    I dont think the fault is temperature induced , mine failed during the summer last year so i doubt it could be induced just by cold weather.

    Yeah. I still havn't had time to take a look at it yet as it's only done it once in the last week and it's been down to 2.5C outside without the fault.

    Still havn't looked at this problem as it hadn't happened for a week or so, then today it threw up the light on the right hand side of the dash, Exhaust Emmisions. When scanning the fault was P0105 and P1105 again. I pressed erase and the light went out.

    Why would that light come up on the dash and not the usual car/spanner light?

    Haven't posted in a while as I had to get a new battery about a month ago, and since then, the fault hasn't re-occurred!

    I did notice that the fault happened mostly when idling or when the engine was under a lot of load, so maybe the old battery was bringing the voltage down a bit and therefore getting incorrect signals back from the MAP sensor.

    Anyway, it seems OK now.....Time will tell
