Sidekick L4-1324cc 1.3L SOHC 5 Carb 8V (1989)
Engine Control Module: Testing and Inspection
Sensors & Lead Wires
The feedback system uses the following sensors: wide open microswitch, idle microswitch, thermal switch, high altitude compensator, thermal engine
compartment switch and fifth switch. If any of these sensors malfunctions or if a sensor circuit is interrupted, the feedback system will not function
properly since the ECM is not receiving a signal. Check each sensor and its circuit as follows:
1.
Turn ignition off.
2.
Disconnect ECM connector.

3.
Connect ohmmeter between terminal 4 of ECM harness connector and terminal 1 (ground), Fig. 19, and measure resistance. Repeat with terminals
5, 11, 14, 15 and 19.
