Even with a basic code reader, the live data should give you throttle position. Just plug in the reader, turn on ignition (engine on or off doesn't matter) go to live data, and try pressing the throttle.

Hi All,
Thanks for all your comments. I spoke to Brian on Friday, what a really helpful guy, and he's given me a few other things to try. But think it will be ECU over to him to check. Cheers, Graham. |

Excuse me asking but why do the 2 capacitors show different voltages ?
Sir

There is only one capacitor fitted to the late ECM, and a blocking oscillator is fitted in place of capacitor two to generate approximately 30v. The NNN100692 as fitted to the early manual cars, has two identical injector driver circuits, so both capacitors read approximately 80v The injector solenoids are 12v, and the ECM generates the injector dwell time with pulse width modulation, using the 80v rail chopped rapidly. There you go, bet you wished you hadn't asked now  Brian  |

On the overview shot of yr t4 the battery voltage is showing as 13.81/13.91 On my obd mode my battery is shown at a similar rate - would this be roughly the correct or necessary rate of charge m8 ? Regards Chris |

Add into the equation I had just programmed the ECM, which involves having the ignition switch in position 2 with the engine not running, so glowplugs and fuel pumps all take their toll on the battery. The normal readings are circa 14.2v, and my car quickly recovered to this after a couple of minutes. If a battery has diminished capacity, it will accept a surface charge very quickly, however as the battery is good on my test car, it is slower to react. Brian |
