    I'm having a problem with the above vehicle, which intermittently looses any throttle response . When this fault occurs the idle speed rises to 1100revs. The difficulty is that the fault is intermittent. Fault codes logged each time are: 74240 Throttle position sensor G69 Signal too low P0122 Lower limit reached intermittent and 139776 Angle sensor 2 for throttle G188: Signal too low. Lower limit reached intermittent. I have once had the fault occur with me and on live data my scanner (Snap On Modis Edge) showed the ECU receiving the correct input from the throttle pedal but no movement at the throttle body. I have checked and cleaned (both looked fine) the plugs at the ECU and the throttle body. I would be keen to test the values at the throttle body but I'm having difficulty finding information on the pin assignations and values for them. If I can't find the relevant information my next move is to physically check the harness from the ECU to the throttle body. I would prefer not to do this without some more evidence..... Any help would be much appreciated. Engine code is BLF

    Not sure about the accuracy of those codes but it looks like a faulty throttle body.
