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 (15) on the PCM doesn't always mean
there's an electrical problem in the mainshaft or
countershaft speed sensor circuit; code P0715 (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 2P connector from the mainshaft
speed sensor.
3. Measure mainshaft speed sensor resistance at the
sensor connector.

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.
