TDC sensor — check (Mitsubishi Lancer 3)

The TDC sensor is located on the distributor and sends a pulse signal to the control unit as soon as the piston of cylinder 1 reaches the TDC ignition position. If the sensor fails, the control unit is unable to maintain the required injection sequence. The engine runs unevenly, stalls, and does not accept gas.



Disconnect the 6-pin connector (A). Connect a voltmeter to contact 2 of the cable part of the connector and to ground (e.g. engine block). Turn on the ignition. Required value: 11-13 V. Turn off the ignition.

Connect an ohmmeter between contact 1 and ground. Resistance should be 0 Ohm, turn off ignition.

Check the output voltage. To do this, connect a voltmeter to contact 4 and ground. Turn on the ignition. The required value is 4.8 5.2 V. Turn off the ignition.

Differences in connector pinout:

• 1.5L engine, manufactured from 9.88 to 8.90: power supply = terminal 3; mass = contact 2; output - contact 4.
• 16-valve engine, production from 9.88 to 8.90: power supply = contact 2; mass = pin 1; output = pin 3.
• 16-valve engine, production from 9.90 to 2.92: power supply = contact 3; mass = pin 4; output - contact 1, see also connector (B) in Fig. K-2210.
