Diagnostic Trouble Code (DTC) Charts


Special Tool(s)
Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool

Using a scan tool to retrieve DTCs, begin with and repair all non-transmission related DTCs. Start with the U-DTCs (communication link codes) and repair any transmission related DTCs.

Limp-home mode is a default condition to protect the engine and transmission when a fault occurs. Limp-home mode depends on the actual gear the vehicle was in when the fault has occurred.

The limp-home gear is held until the vehicle is placed in REVERSE, PARK or the vehicle is restarted. After these action(s) the vehicle defaults to the limp-home mode of 3rd gear.

REPAIR the more specific DTC first. GO to Pinpoint Test C .
P1711 TFT sensor TFT sensor out of self test range The PCM did not receive a TFT sensor input during the Key ON Engine OFF (KOEO) or Key ON Engine Running (KOER) self-test that was within -1.11°C to 104°C (30°F to 220°F) during the self-test.
CLEAR the DTC. RERUN the KOEO and KOER self test. If DTC returns GO to Pinpoint Test B .
P1744 TCC TCC solenoid circuit The PCM has detected that the TCC solenoid is stuck ON or OFF.
  • MIL ON
  • TCIL flashing
  • Wrench light illuminated

DTC P1744 is a non-electrical DTC. REPAIR the more specific DTC first. CLEAR the DTCs. TEST the system for normal operation. If the DTCs return, REFER to Diagnosis By Symptom in this section.
P1780 Transmission Control Switch (TCS) TCS (O/D cancel) circuit out of self-test range The PCM did not receive a TCS input during the KOER self-test.
  • MIL ON
  • Disable overdrive cancel function
CLEAR the DTC. RERUN KOER self test. If DTC returns, REFER to Section 307-05 .
P1783 Transmission Transmission overtemperature condition The PCM detected a transmission temperature greater than 135°C (275°F) for more than 5 seconds.
  • TCIL flashing
  • TCC commanded on early
CLEAR the DTC. TEST the system for normal operation. If the DTC returns, REFER to Diagnosis By Symptom in this section.
P1910 PCM Reverse lamp control circuit/open The TR sensor sends a signal to the PCM when reverse is selected. The PCM then controls an output which energizes the reverse lamp relay.
  • MIL ON
  • Reverse lamps do not function properly
CLEAR the DTC. TEST system for normal operation. If DTC returns, REFER to Section 417-01 .
P1921 TR sensor TR signal The PCM has detected a TR signal duty cycle out of range.
  • Engine will not crank
  • MIL ON
  • DTC P1705, DTC P0706, DTC P0707, DTC P0708 or DTC P0709 may set
REPAIR the more specific DTC first. GO to Pinpoint Test C .
