Motor anlernen, wenn Batterie leer ………. When engines have to learn

Teach the engine when the battery is dead …….

My 1991 TVR S3C with the 2.9 liter Ford Koln V6 has about 450,000 miles on the clock. The the same engine was also in the Scorpio or Sierra. The TVR runs well, the engine hangs perfectly on the gas, has no temperature problems and also starts perfectly. When the engine is up to operating temperature, however, the idling increases to 1500 to 2000 V/min, which then means that the crate has to be almost stalled when driving slowly via the brakes. At normal speed everything is fine. When I turn off the ignition and switch it on again immediately, the idle state is back on normal range at 800 to 1000 V/min. After a short drive, the spook starts all over again. falls to you something about that?

With your TVR, too, the error memory should first be queried with blink code output. You will probably find the idle contact in the throttle valve potentiometer to be the cause here. As a result, the engine control unit temporarily does not receive the idling information at all and the electronic idling actuator works uncontrolled. The potentiometer must either be readjusted or replaced. After the repair, equipotential bonding must be carried out by removing the battery connection cables and briefly holding them together. This clears the on-board computer. The motor control must then be taught in again. To do this, the engine should run at idle for at least three minutes before the speed is increased to 1200 rpm for two minutes. Then a journey of at least eight kilometers must follow. During this process, the control unit measures and recognizes its sensors and is then ready for use again. Incidentally, the same procedure is required every time the battery is completely disconnected.
