    2012 Abarth with new P1185 & P0069 Codes

    So I'm still getting to know my new (to me) Abarth. Drives fantastic and makes great power. No issues until last night, when while driving on the highway, the engine turned off, at 70mph. Multiple attempts to restart the engine failed, until i pulled the key and opened the drivers door, at which point it started again but with a CEL and it felt funny. After getting to a safe place, i plugged in an OBD reader and found codes P1185 and P0069. i tried clearing the code, but it wouldn't delete. and when eventually i did get it clear, the car wouldn't start again for 4 attempts,. and when it did, the light was of course back on.

    I drove the car back home, now with no cruise control, which was fun. also the Torque app was now showing a constant 22psi of boost, and the OEM (likely useless?) gauge shows 1psi at idle, and 12-18psi when driving around slowly, in a way that would usually show no boost at all. my first thought was to put in a new MAP sensor, which did nothing at all to solve this problem.

    to add to the fun, I'm still not 100% on what has been done to this car, form what i have found so far is a Road Race Motorsport piggyback tuner, a Sila FMIC, a Madness Intake, a Forge wastegate, and some sort of boost solenoid. also worth noting is that this car has a bilstein coilover suspension, and i was driving on the worst roads in America, bouncing me and the car all over the place. and the engine was running flawlessly up until then. Please help, I'm out of ideas, and so is my mechanic.

    An update: now the car will not run, idles real rough for a minute or so, then stalls. The boost gauge is jumping around its full range of motion the whole time. <br/><br/>
    Update 2: it has now started and is running, not great, but good enough to get me home it seems. I have what appears to be a bypass plug for the tun, but I have no idea where to plug it in. Any ideas?

    I don't use those mods, but there were posts saying the P0069 can be caused by a bug in the RRM. The recommended "fix" was to disconnect the negative battery terminal, leave it off for 5+ minutes, then reconnect. It can take the computer a bit of time to "relearn", but that is supposed to clear that code immediately. The relearn curve can take 20 to 80 miles of easy driving.

    Unless you have an aftermarket meter, the boost meter readings are a guess, not an actual manifold pressure; it's what the computer thinks is going on and close enough for entertainment value. As I understand it, with the error is because the computer is testing reality (atmosphere) to its imagined pressure. I hope that works.

    Here's the install of a Roadrace ECU showing how to hook up the bypass plug near the end of the video:

    Ok I tried unhooked the battery, left it for about 15 minutes, then hooked it up again. Took 4 attempts to start, and then threw the same codes, plus a new one p2261. Also, my road race box looks different from that one, and has 2 cables, hard wired into smaller black plastic box. <br/><br/>thank you both for your help. Does anyone else have any ideas?

    Here is a similar thread... boost sensor problem (MAP) & P1185. The P0069 can be this sensor... but check for vacuum leaks and replace your air filter if it's dirty.

    This is the 2.4L multiair for the P1185. Jump to 1:15 to avoid the lead-up.


    Naturally, you'll want to test it before throwing on a new one. Usually you'd use a scan tool to diagnose, but it can be done off or in the car with a vacuum gauge and Ohm meter. Youtube has some good vids explaining how to test and what other systems can cause false readings.

    Does your Abarth have a Go Fast Bits DV+ installed on it?

    I've had a GFB DV+ installed on my 2012 for a long time now. Every so often (like once or twice a year) the car will throw a p2261 code "Turbocharger/supercharger Bypass Valve-Mechanical". It usually happens when I jump of the gas pedal abruptly just as the engine is ramping up boost during acceleration. I think this is when the GFB DV+ is most likely to malfunction due to being dirty and sticky.

    When the car throws this code I know it's time to disassemble the GFB DV+ and clean it up and put some grease on the brass cylinder. After this cleaning and greasing of the GFB DV+ the car will not throw the p2261 code again for about 6 months to a year (and when it eventually does it again I'll clean and re-grease again).

    The whole process of removal and cleaning/re-greasing only takes about 20 minutes to do.

    Ok, so here is the final resolution of this little mess: While removing the piggy back tuner to bring the car back to stock so i could begin firing the parts cannon at it, i found this

    this harness was running to the Boost pressure sensor on the intercooler piping. So i de-pinned the connector, trimmed everything back a bit, crimped on new pins, re-pinned the connector, plugged it back in, and then restarted the car. Happily, i found that the P1185 and P2261 codes were gone, but the P0069 remained. Out of pure frustration, i pulled out the new MAP sensor, and put back in the original, and behold, Victory was mine, no codes. Took the car out and it drove fantastic. So well in fact that i treated it to some new tires. which incidentally make me hate the Bilstein coilovers a lot less. Thank you all again for your help.

    That is weird. I wonder how the wires got cut; doesn't look like a rodent. Which connector is that?

    Also, what brand of MAP sensor was the new one? I suppose the new sensor wasn't connected, but sometimes new parts are defective.

    Wasn't cut, the insulation on the end of the wire by the connector had dried out and gone brittle, and the wire was corroded. just snapped, id blame the brutal roads in Queens, combined with the insanely stiff sidewalls on the old Falken Azenis tires and Bilstein suspension, musta just hit one hard bump too many.

    Did inspect the other wires in the area, and they were all fine. And it was one of the Boost Pressure Sensor connnectors. As for the MAP sensor it was a POS from Santech. all i could find on short notice. Regardless, it was returned.
