    Inlet manifold preassure sensor fault code

    Does anyone have any experience of this issue ?
    Fault code 'p0108 sensor 1 high voltage'
    The sensor is on the inlet manifold vacuum.
    The diagnosis was made on dealer tool and when reset re appears almost immediately.

    Nothing to fear but fear itself!

    The following information is drawn from the Service Manual for DTC P0108 -
    "Manifold Absolute Pressure ( MAP ) Sensor 1 open circuit or short circuit to 5 volt sensor supply"

    The MAP Sensor is situated to the left side of the airbox,
    connected to each of the three throttle bodies by equal length tubes.
    ( See below image ).

    The ECM is located under the headlamp - access is gained by removing the front cockpit panel.

    NOTE: Before commencing the following tests switch off the Ignition and wait for AT LEAST 1 minute
    to allow the ECM to complete it's Power Down sequence, then disconnect the main battery.

    Pinpoint tests :

    1.  Disconnect ECM and MAP sensor

    2.  Check for short circuit between ECM pin B36 and ECM pin B34.
         If OK - Renew MAP Sensor and proceed to Test 3.
         If Short circuit, locate and rectify wiring fault, then proceed to Test 4.

    3.  Check cable continuity from ECM pin B36 to MAP Sensor pin 2,
         and from ECM pin B18 to MAP Sensor pin 1.
         If OK - Renew MAP Sensor and proceed to Test 4.
         If Open circuit, locate and rectify wiring fault, then proceed to Test 4.

    4.  Reconnect harness to ECM and MAP Sensor, clear fault code and run engine.
         If OK - Actions complete - quit test.
         Fault still present - Contact Triumph Service.

    I think the MAP Sensor is the one shown as Item 6 here : World of Triumph - Engine Management System
    but please confirm with your Dealer etc. before purchasing one !

    Hope this helps  :821:

    I had a fault code P0108. Changed air pressure sensor (part No. PFKL2040454), tested about 300km - everything ok. It is enough to remove left side fairings to change this sensor

    This is quite an old Topic now, but the information is still quite useful !  :028:

    The part number you quoted is World of Triumph's unique Part Number.

    The Triumph Part Number is T1290975.

    Cheers  :821:
