Section 06 ENGINE MANAGEMENT (4-TEC)
Subsection 03 (COMPONENT INSPECTION AND ADJUSTMENT)
Disconnect plug connector from MAPS and con-
nect a voltmeter between pin 1 and 2.
Install the tether cord cap, then depress the cut-
out switch and push start button momentarily to
activate the ECM. The measure should be 5 Vdc
on the voltmeter.
If voltage test is good, replace the MAPS.
If voltage test is not good, check the continuity of
the MAPS circuit.
Resistance Test
Disconnect the connector A from the ECM.
Using a multimeter, check continuity of circuits 12,
28 and 40.
If wiring harness is good, try a new ECM. Refer
to ECM REPLACEMENT procedures elsewhere in
this section.
Otherwise, repair the connectors or replace the
wiring harness between ECM connector and the
MAPS.
Verification Test
Using VCK, energize the MAPS from the MONI-
TORING section and read out the proper pressure
value while engine is stopped.
Perform the same test with a new MAPS and
comparebothreadings.
Values have to be within ± 3.4 kPa (0.5 PSI).
If old MAPS's value is out of this range, replace it.
Replacement
Disconnect MAPS connector and remove the
MAPS.
Install the new MAPS paying attention to index
its tab into the adaptor notch. Apply Loctite 243
(blue) on screw then torque to 6 N•m(53lbf•in).
OIL PRESSURE SWITCH (OPS)

1. OPS
Oil Pressure Test
To check the function of the oil pressure switch,
an oil pressure test has to be performed. Refer to
OIL PRESSURE TEST in LUBRICATION SYSTEM
section.
If the engine oil pressure is out of specifications,
check the points described in troubleshooting sec-
tion.
If the engine oil pressure is good, check the re-
sistance of the OPS while engine is off and while
engine is running.
Resistance Test
Disconnect the plug connector from the OPS
and use a multimeter to check the resistance be-
tween OPS pin and engine ground while engine
is stopped (without oil pressure) and while engine
is running (with oil pressure).
When engine is stopped the resistance is close to
0
(normally close switch).
When engine is running and the oil pressure reach-
es 20 - 40 kPa (2.9 - 5.8 PSI), the resistance of the
OPS is infinitely high.
If resistance values are incorrect, replace OPS.
If the values are correct, check the continuity of
the wiring harness.
Disconnect the connector A from the ECM and
check continuity of circuit 10.
