DTC P0715: Problem in Mainshaft Speed
Sensor Circuit
NOTE: Record all freeze data and review General
Troubleshooting Information (see page 14-3) before
you troubleshoot.
Code P0715 (code 15) on the PCM doesn't always mean
there's an electrical problem in the mainshaft or
countershaft speed sensor circuit; code P0715 (code 15)
may also indicate a mechanical problem in the
transmission. Any problem causing irregular
countershaft to mainshaft speed difference can cause
this code.
1. Check the mainshaft and countershaft speed
sensor installation.
Are the mainshaf t and the countershaf t speed
sensors installed properly?
YES Go to step 2.
NO Reinstall and recheck.
2. Disconnect the mainshaft speed sensor connector
(2P).
3. Measure the mainshaft speed sensor resistance at
the sensor connector.

YES Go to step 4.
NO Replace the mainshaft speed sensor (see
page 14-134).
4. Disconnect PCM connector C (22P).

Is there continuity?
YES Repair short in the wires between PCM
connector terminals C6 and C7, and the mainshaft
speed sensor.
NO Go to step 6.
6. Connect the mainshaft speed sensor connector.
7. Measure the resistance between PCM connector
terminals C6 and C7.

Wire side of female terminals
Is there 400 600 ?
YES Run the Electrical Troubleshooting Flowchart
for code P0720 (code 9). Check for loose terminal fit
in the PCM connectors. If necessary, substitute a
known-good PCM and recheck.
NO Go to step 8.
