TROUBLESHOOTING [GF4A-EL]
DTC P1765 3 -2 timing solenoid valve malfunction
DESCRIPTION
• Damaged wiring or connectors between 3 -2 timing solenoid valve and powertrain control module
• Short or open circuit in 3 -2 timing solenoid valve
• Short or open circuit in powertrain control module internal transistors
POSSIBLE
CAUSE
• Damaged wiring or connectors between 3 -2 timing solenoid valve and powertrain control module
• Short or open circuit in 3 -2 timing solenoid valve
• Short or open circuit in powertrain control module internal transistors
STEP
INSPECTION ACTION
1 Are powertrain control module and 3 -2 timing
solenoid valve connections at connector and
connector pins okay? Yes Go to next step
No
Repair or replace connector(s), then go to step 7
2 Check NGS tester display
• Connect NGS tester to data link connector
• Are 3 -2 timing solenoid valve operation and
NGS tester display correct?
tr 0 1 -40B POWERTRAIN CONTROL
MODULE (PCM) INSPECTION [KL]
Yes Go to step 7
No Go to next step
3 Check for continuity between terminals of 3 -2
timing solenoid valve and powertrain control
module
• Disconnect negative battery cable
• Disconnect solenoid connector and powertrain
control module connector
• Is there continuity between terminals?
Yes Go to next step
No Repair or replace connectors and wiring, then go to step 7
4 Check for a short circuit between terminals of 3 -2
timing solenoid valve and powertrain control
module.
• Disconnect solenoid and powertrain control
module connectors
• Connect ohmmeter between GND and 3 -2
timing solenoid valve connector terminal
• Is continuity present?
Yes Repair short circuit, then go to step 7
No Go to next step
5
Measure resistance at 3 -2 timing solenoid valve
terminal
• Disconnect negative battery cable
• Disconnect solenoid connector
• Is resistance correct?

REMOVAL/INSTALLATION [GF4A-EL]
6 After diagnostic trouble code has been cleared,
recheck If diagnostic trouble code is shown
v 0 1 -0 1 B ENGINE ON-BOARD DIAGNOSIS
[KL]
Yes Return to step 2
No
Problem is a temporary poor connection of wiring or
connectors, and should be investigated further, then go to
next step
7 Erase diagnostic trouble code from memory. Can
code be output after performing “After Repair
Procedure”?
Yes
Go to appropriate inspection procedure
No
