We've just replace the engine in a 2006 2.4l Rav 4. Replacement engine uses all the (tested) sensors from the old engine. Ran all the continuity / voltage checks for the ignition circuit and all are ok; Crank sensor and Cam sensor check ok. However, there is a constant 4.7volt signal between all ITG terminals and ground ie ignition coil connector terminals 2 and 4. We have re-set the ECM and no codes are showing. There is a smell of gasoline so we assume the injectors are working. Question: What could cause the ECM to send a constant 4.7 volt signal to all ignition coils constantly? Thanks in advance.
