Step
2 Check pressure control solenoid valve resistance
1) Turn ignition switch OFF
2) Disconnect valve body harness connector on
automatic transmission.
3) Check for proper connection to solenoid at
"BRN/YEL" and "LT GRN/RED" circuit.
4) Check resistance of pressure control solenoid.
See Fig.
Resistance between pressure control solenoid
valve terminals of transmission side valve body
harness connector:
5.0 – 5.6 Ω
Resistance between pressure control solenoid
valve terminals of transmission side valve body
harness connector and transmission body:
Infinity
Is check results satisfactory?
3 Check pressure control solenoid valve circuit for
ground short
1) Connect valve body harness connector.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at termi-
nals "E13-2" and "E13-4".
If connection is OK, check continuity between ter-
minal "E13-4" of disconnected harness side TCM
connector and ground.
Is continuity indicated?
4 Check pressure control solenoid valve circuit for
open
1) Check resistance between terminals "E13-2"
and "E13-4" of disconnected harness side
TCM connector.
Is it infinity?

Go to Step 4.
Intermittent trouble or
faulty TCM. Check for
intermittent referring to
"Intermittent and Poor
Connection" in Section
0A. If OK, substitute a
known-good TCM and
recheck
