FE02-5020b
(a)
Turn the ignition switch to "OFF" position.
(b)
Disconnect intake manifold absolute pressure sensor wiring
harness connector EN16.
(c)
Disconnect ECM harness connector EN01.
(d)
Measure the resistance between intake manifold absolute
pressure sensor harness connector EN16 terminal No.3 and
ECM harness connector terminal No.19. Check whether the
circuit is open. If there is no open circuit, repair the faulty part.
(e)
Measure the resistance between intake manifold absolute
pressure sensor wiring harness connector EN16 terminal No.
3 and a reliable ground. Check whether there is a circuit short
to ground . If there is no short circuit, repair the faulty part.
(f)
Measure the voltage value between intake manifold absolute
pressure sensor wiring harness connector EN16 terminal No.
3 and a reliable ground. Check whether the circuit is short to
power supply. If there is no short circuit, repair the faulty part.
