Attention! In the ignition system, high voltage is generated. Be careful, observe all necessary precautions when servicing any system components, including not only the main (ignition module, coil, distributor and explosive wires), but also related, such as candle connectors, a tachometer and other equipment.
Programmable ignition system (PGM-IG) based on a microprocessor ensures constant optimization of the ignition timing depending on engine speed, coolant temperature, throttle position and depth of depression in the intake manifold. All necessary data is sent to the onboard processor control module (RSM) from relevant information sensors such as the crankshaft position/TDC sensor (TDC/TFR), piston position sensor (CYP), throttle position sensor (TPS), electronic coolant temperature sensor (EATING) and an absolute pressure sensor in the pipeline (IDA). When the engine is warming up, idling and under load, different ignition timing settings are used. Appropriate adjustments are made by the PGM-IG system. The ignition system also includes an ignition switch/lock, battery, ignition coil, distributor, ignition control module (ICM), a set of spark plugs and BB wires on 4-cylinder models, the ignition coil is built into the distributor, while on V6 models it is installed outside, next to the latter.
The distributor of ignition on all models is put in action from a camshaft. The ignition timing is corrected by the electronic engine control module (RSM). All models are equipped with a crankshaft position sensor (TFR), which is installed under the lower timing belt cover, next to the crankshaft gear. TDC sensor (TDC) on 4-cylinder models mounted near the CKP sensor (in front of him); V6 models have two TDC sensors, #1 and #2, mounted behind the camshaft gears at the front end of the cylinder heads. Piston position sensor (CYP) on 4-cylinder models and the ignition control model on all models is mounted inside the distributor. For all questions, please contact the specialists of the car service.
