    Puma Oil Temp

    I'm getting erratic oil temp readings on my 2.2L Puma on a Nanocom. Temp flicks between -20deg up to 180deg.
    I'm thinking its the sensor but before I replace it.....


    Do you get normal or abnormal oil temp readings?


    Which type of device are you using?


    Thanks

    Still trying to get to the bottom of this...anyone with a 2.2L Puma and Nanocom that can help out?
    Interestingly the BAS tool doesn't have the option to read oil temp...I wonder why that is?
    Thanks

    I've seen this in my vehicle.
    Never got around to looking into the solution either.
    Then again, haven't had a look at it since I first noticed the problem.

    Thread here http://www.aulro.com/afvb/electronic...ervations.html

    Are you getting any P codes on the nanocom?

    Thanks, I'm assuming a new sensor will fix it too, just seems quite a few people have the issue and am yet to hear of anyone resolving it.

    Sierrafery you are the first to report a resolution!!

    Once it did throw a code saying it was either a sensor or wiring problem, I don't understand why it doesn't keep throwing it though...probably should just bite the bullet on a new sensor and see I guess...

    Usually the ECU will store a code for open circuit, closed to earth or if the reading is out of the map's limit values, if the behaviour is erratic but it gives readings within the accepted limits it will just mix up the management but might not throw a fault code, the oil temp sensor is hardwired to the ECU so unless the wiring is chaffed somewhere or there's bad contact in the plugs the problem is most likely bad sensor, at least that's what it was on my friend's Puma.... anyway, to chase a wiring issue on that circuit could be a nightmare so you better rule out the sensor first then if the problem persists you can go further IMO
