Aika hassussa ajotilanteessa on mielestäni koodi tullut. Toi solenoidihan on kaiketi toiminnassa silloin kun ajetaan tasaista n.80km/h nopeutta ja halutaan ohjelmalla poistaa kaikki ylimääräinen luisto jotta polttoainetta säästyisi. Sanotaan kaiketi myös turbiinin lukkosolenoidiksi. Täytyskin oikein ottaa ja tarkastaa faktat vielä
Onko vika vaivannut sittemmin ?
EDIT: No tossahan se oli:
OBD Code P0740refers to
The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled. When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter. Lock-up operation, however, is prohibited when A/T fluid temperature is too low. When the accelerator pedal is depressed (less than 2/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.
