Control System JL4G18-D
(a) Turn the ignition switch to "OFF" position.
(b) Disconnect intake manifold absolute pressure sensor wiring
harness connector EN16.
(c) Turn the ignition switch to "ON" position.
(d) Measure intake manifold absolute pressure sensor wiring
harness connector EN16 terminal No.3 to a reliable ground
voltage.
Standard Voltage: 4.5V-5.5V
(e) Connect intake manifold absolute pressure sensor wiring
harness connector EN16.
Is voltage the specified value?
Go to step 6
No
(a) Turn the ignition switch to "OFF" position.
(b) Disconnect intake manifold absolute pressure sensor wiring
harness connector EN16.
(c) Turn the ignition switch to "ON" position.
(d) Between EN16 terminal No.3 and No.4, connect a 5A fuse
wire. Use scan tool to read "the actual intake manifold
absolute pressure sensor voltage" parameter.
Standard Parameter: 4.5V-5.5V
(e) Connect intake manifold absolute pressure sensor wiring
harness connector EN16.
Is data normal?
Go to step 7
No
