Radiator

Cap Testing

1. Remove the radiator cap, wet its seal with engine

coolant, then install it on the pressure tester.

2. Apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm2,

14- 18
psi).

3. Check for a drop in pressure.

4. If the pressure drops, replace the cap.

1. Wait until the engine is cool, then carefully remove

the
radiator
cap and
fill
the
radiator
with
engine

coolant to the top of the filler neck.

2. Attach the pressure tester to the radiator and apply

a pressure of 93-123 kPa (0.95 - 1.25 kgf/cm2, 14 -

18
psi).

3. Inspect for engine coolant leaks and a drop in pres-

sure.

4. Remove the tester and reinstall the radiator cap.

NOTE: Check for engine oil in the coolant and/or

coolant in the engine oil.

Powertrain Control Module (PCM)

NOTE: If this symptom is intermittent, check for a loose fuse No. 1 (BACK UP

LIGHTS, METER LIGHTS, 10 A) in the under-dash fuse/relay box, a poor con-

nection at PCM terminal A7, or an intermittent open in the GRN/RED wire

between the PCM (A7) and the gauge assembly.

Is the low oil pressure light on?

Try to start the engine.

Does the engine start?

Check for an open in the wire or

bulb (MIL line):

1. Turn the ignition switch OFF.

2. Connect the PCM connector ter-

minal A7 to body ground with a

jumper wire.

3. Turn the ignition switch ON (II).

Is the MIL on?

Substitute a known-good PCM,

and recheck. If symptom/indica-

tion goes away, replace the origi-

nal
PCM.
— Repair short or open in the

wire between NO. 1 (BACK-UP

LIGHTS, METER LIGHTS) (10

A) fuse and gauge assembly.

— Replace No. 1 (BACK-UP

LIGHTS, METER LIGHTS) (10 A)

fuse.

PCM CONNECTOR A (26P)

Check for an open in the wires

(PG1, PG2 lines):

1. Turn the ignition switch ON (II).

2. Measure voltage between

body ground and PCM con-

nector terminals A12 and A25

individually.
Wire side of female terminals

Is there less than 1.0 V?
Repair open in the wire(s)

between PCM and G101 (located

at intake manifold) that had

more than 1.0 V.

PCM CONNECTOR A (26P)

JUMPER WIRE

Wire side of female terminals
Repair open in the wires

between PCM (A7) and gauge

assembly.

Replace the MIL bulb.
Substitute a known-good PCM

and recheck. If symptom/indica-

tion goes away, replace the origi-

nal
PCM.
Turn the ignition switch ON (II).
The Malfunction Indicator Lamp

(MIL) never comes on (even for

two seconds) after ignition is

turned on (II).ProCarManuals.com

12. Coat new seal rings with clean engine oil and press them into the intake manifold.

13. Install the fuel injectors and fuel rail assembly in the intake manifold.

CAUTION: To prevent damage to the O-ring, install the fuel injectors in the fuel rail first, then install them in the

intake manifold.
