Control System JL4G18-D
(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 resistance between intake manifold absolute
pressure sensor harness connector EN16 terminal No.4 and
ECM harness connector terminal No.59. Check whether the
circuit is open. If there is no open circuit, repair faulty part.
(e) Measure resistance between intake manifold absolute
pressure sensor harness connector EN16 terminal No.4 and
a reliable ground. Check whether the circuit is short to
ground. If there is no short circuit, repair faulty part.
(f) Measure voltage between intake manifold absolute pressure
sensor harness connector EN16 terminal No.4 and a reliable
ground. Check whether the circuit is short to power supply. If
there is no short circuit, repair faulty part.
