Problem in Countershaft Speed
Sensor Circuit
NOTE:
• Record all freeze data and review General
Troubleshooting Information (see page 14-3) before
you troubleshoot.
• This code is caused by an electrical circuit problem
and cannot be caused by a mechanical problem in the
transmission.
1. Check the countershaft speed sensor installation.
Go to step 2.
Reinstall and recheck.
2. Disconnect the countershaft speed sensor
connector (2P).
3. Measure the countershaft speed sensor resistance
at the sensor connector.
Go to step 4.
Replace the countershaft speed sensor (see
page 14-134).
4. Disconnect PCM connector C (22P).
5. Check for continuity between PCM connector
terminal C14 and body ground, and between
terminal C15 and body ground.
Repair short to ground in the wires between
PCM connector terminals C14 and C15, and the
countershaft speed sensor.
Go to step 6.
6. Connect the countershaft speed sensor connector.
7. Measure the resistance between PCM connector
terminals C14 and C15.
Check for loose terminal fit in the PCM
connectors. If necessary, substitute a known-good
PCM and recheck.
Repair loose terminal or open in the wires
between PCM connector terminals C14 and C15,
and the countershaft speed sensor.
