Electrical Troubleshooting

Troubleshooting Flowchart — A/T Clutch Pressure Control Solenoid Valve

• OBD II Scan Tool indicates Code

P0748.

• Self-diagnosis indicator light

indicates Code 16.

Measure A/T clutch pressure con-

trol solenoid valve Resistance at

Solenoid Connector:

1. Disconnect the shift solenoid

valve/A/T clutch pressure con-

trol solenoid valve harness 4P

connector.

2. Measure the resistance of the

A/T clutch pressure control

solenoid valve.

Is the resistance approx. 5 ?

YES

Check A/T Clutch Pressure

Control Solenoid Valve for a

Short Circuit:

1. Disconnect the E (26P) con-

nector from the PCM.

2. Check for continuity between

body ground and the E16 termi-

nal and E3 terminal individually.

Is there continuity?

NO

Measure A/T Clutch Pressure

Control Solenoid Valve Resistance:

1. Connect the shift solenoid

valve/A/T clutch pressure con-

trol solenoid valve harness 4P

connector.

2. Measure the resistance

between the E16 and E3 ter-

minals.

Is the resistance approx. 5 ?

YES

Check the VB SOL Voltage:

1. Disconnect the A (26P) and E

(26P) connectors from the

PCM.

2. Turn the ignition switch ON (II).

3. Measure the voltage between

the E1 and A26 terminals.

Is there voltage?

YES

Check for loose PCM connectors.

If necessary, substitute a known-

good PCM and recheck.
Possible Cause

• Disconnected A/T clutch pres-

sure control solenoid valve con-

nector

• Short or open in A/T clutch

pressure control solenoid valve

wire

• Faulty A/T clutch pressure con-

trol solenoid valve

• Open VB SOL line

Replace the A/T clutch pressure

control solenoid valve.

Repair short in the wires

between the E16 and E3 termi-

nals and the A/T clutch pressure

control solenoid valve.

Repair loose terminal or open in

the wires between the E16 and E3

terminals and the A/T clutch pres-

sure control solenoid valve.

Check for open in the wire

between the E1 terminal and the

under-hood fuse/relay box.ProCarManuals.com

Planetary Gear Inspection

Check if the planetary gears are worn or damaged. If they

are, also check the condition of the armature shaft gear

and ring gear.

Overrunning Clutch Inspection

Slide the overrunning clutch along the shaft.

Does it move freely? If not, replace it.
1.

2.
Rotate the overrunning clutch both ways.

Does it lock in one direction and rotate smoothly in

reverse? If it does not lock in either direction or it

locks in both directions, replace it.

DRIVE GEAR

If the starter drive gear is worn or damaged, replace

the overrunning clutch assembly; the gear is not avail-

able separately.

Check the condition of the torque converter ring gear

if the starter drive gear teeth are damaged.ProCarManuals.com
