Section 06 ENGINE MANAGEMENT (4-TEC)
Subsection 03 (COMPONENT INSPECTION AND ADJUSTMENT)
Check the resistance between pin 1 and pin 4 and
alsobetweenpin3andpin2oftheidlebypass
valve.
The resistance in each winding should be approx-
imately 50 at 23°C(73°F).
If the resistance of one or both windings is not
good, replace the idle bypass valve.
If resistance test of valve windings is good, check
continuity of circuits A-35, A-36, A-37, A-38.
Visual Inspection
NOTE: Make sure the tether cord cap is removed
during the following procedure.
Remove idle bypass valve from throttle body.
Check the piston and bypass channel for dirt/de-
posits which can cause a sticking piston.
CAUTION: Always keep the tether cord cap dis-
connected, while the idle bypass valve is re-
moved.
CAUTION: Do not try to operate the piston of
the idle bypass valve when it is dismounted.
Also do not move the piston by hand. The
drivescrewisverysensitiveandmaybede-
stroyed.
Using a part cleaner, clean idle bypass in throttle
body from contamination then use an air gun to
dry it.
WARNING
Always wear eye protector. Chemicals can
cause a rash break out and injure your eyes.

1. Clean bore from contamination
Clean all remaining parts and install the idle bypass
valve on the throttle body.
Proceed with the CLOSED THROTTLE AND IDLE
ACTUATOR RESET. See above.
CRANKSHAFT POSITION
SENSOR (CPS)

1. CPS connector
NOTE: Take into account that a CPS fault can be
triggered by bent or missing encoder wheel teeth.
First check fault codes then check the teeth con-
dition if necessary. See below.
Disconnect CPS wiring harness connector. Probe
terminals 1 and 2 coming from CPS while cranking
engine. Voltage should be within 1-2 Vac. Other-
wise, inspect wiring and replace CPS if wiring is
good.
Resistance Test
Disconnect the CPS plug connector from the
wiring harness and check the resistance of the
sensor itself.
The resistance should be between 0.7 k
and
1.1 k
.
Otherwise, replace the CPS.
If resistance tests good, reconnect the CPS and
disconnect the connector A on the ECM.
