Go to step 10
Next
(a)
Turn the ignition switch to "OFF" position.
(b)
Disconnect intake manifold absolute pressure sensor wiring
harness connector EO16.
(c)
Disconnect ECM harness connector EO01.
(d)
Measure resistance between intake manifold absolute
pressure sensor wiring harness connector EO16 terminal No.
3 and ECM harness connector terminal No.6. Check whether
the circuit is open. Otherwise, repair the fault part.
(e)
Measure resistance between intake manifold absolute
pressure sensor wiring harness connector EO16 terminal No.
3 and a reliable ground. check whether the circuit is short to
ground. Otherwise, repair the fault part.
(f)
Measure resistance between intake manifold absolute
pressure sensor wiring harness connector EO16 terminal No.
3 and power supply. check whether the circuit is short to
power supply. Otherwise, repair the fault part.
Test Items
