7. Inspect the pre - catalytic oxygen sensor ground circuit
A. Turn the ignition switch to position "LOCK".
B. Disconnect the pre - catalytic oxygen sensor wiring
harness connector E05.
C. The ignition switch is set to position "ON".
D. Measure the resistance value between the pre -
catalytic oxygen sensor E05 terminal 3 and the
reliable grounding.
Standard Resistance Value: less than 5 Ω
E. Connect the pre - catalytic oxygen sensor wiring
harness connector E05.
Is the resistance value normal?
Y
Go to step 8.
N
Repair the circuit between the pre - catalytic oxygen
sensor wiring harness connector E05 terminal 3 and
the ECM wiring harness connector E01 terminal 36.
8. Inspect the air intake pressure sensor MAP
A. Turn the ignition switch to position "LOCK".
B. Connect a vacuum gauge to the air intake manifold
vacuum source.
C. Turn the ignition switch to position "ON".
D. Use a diagnostic tool to read the "actual intake
manifold pressure" data stream.
Is the indication on the diagnostic tool of the vac-
uum meter in the 1 in (25 mm) range?
Y
Go to step 9.
N
Replace the air intake pressure and temperature
sensor, clean the throttle and the air intake mani-
fold.
