(a)
Turn the ignition switch to "OFF" position.
(b)
Disconnect the crankshaft position sensor wiring harness
connector EO26.
(c)
Disconnect ECM harness connector EO01.
(d)
Measure resistance between crankshaft position sensor
wiring harness connector EN26 terminal B and ECM harness
connector EN01 terminal No.20. Check whether the circuit is
open.
(e)
Measure resistance between crankshaft position sensor
wiring harness connector EN26 terminal B and a reliable
ground. Check whether the circuit is short to ground.
(f)
Measure resistance between crankshaft position sensor
wiring harness connector EN26 terminal B and power supply.
Check whether the circuit is short to power supply.
