AUTOMATIC TRANSAXLE (M13 ENGINE) 7B1-71
Fig. for Step 2.
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
(at 20°C (68°F))
Resistance between pressure control solenoid
valve terminals of transmission side valve body
harness connector and transmission body:
Infinity
Is check results satisfactory?
Go to Step 3. Replace pressure control
solenoid valve or valve
body harness.
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?
“BRN/YEL” or “LT
GRN/RED” circuit
shorted to ground. Go to Step 4.
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?
“BRN/YEL” or “LT
GRN/RED” circuit
open. 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
