1A-107 Engine General Information and Diagnosis:
Step
4 Check PNP signal ("D" range signal)
1) Turn ignition switch ON.
2) Check voltage at terminal "G03-6" of ECM connector
connected.
PNP signal
"P" and "N" range: 10 – 14 V
"R", "D", "2" and "L" range: 0 – 1 V
Is 0 – 1 V indicated no matter which of "R", "D", "2" and "L"
range positions selector lever may be at?
5 Is "P/N" range on display (Is 10 – 14 V indicated) when
selector lever is at one of "R", "D", "2" and "L" range
positions only?
6 Check PNP signal circuit
1) Turn ignition switch OFF.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at terminal.
4) If OK, then check voltage at terminal in TCM connector
disconnected, with ignition switch ON.
Is it 10 – 14 V?

Yes
Intermittent trouble or
faulty ECM.
Check for intermittent
referring to "Intermittent
and Poor Connection
Inspection in Section
00".
Check transmission
range sensor and
circuits referring to
"Transmission Range
Sensor (Shift Switch)
Inspection and
Adjustment in Section
5A".
"BLK/RED" circuit open,
poor transmission range
switch connector
connection, select cable
maladjusted,
transmission range
sensor maladjusted or
transmission range
sensor malfunction.
If all above are OK,
substitute a known-
good TCM and recheck.
No
Go to Step 5.
Go to Step 6.
"GRY/RED" circuit open
or poor "G03-6"
connection.
If wire and connection
are OK, substitute a
known-good ECM and
recheck.
