| P1112 | IAT | IAT sensor or circuit signal intermittent. | PCM has detected an intermittent signal. | Incorrect EPC pressure, either high or low which will result in harsh or soft shift. | Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE . |
| P1116 | ECT | ECT out of onboard diagnostic range. | ECT temperature higher or lower than expected during KOEO and KOER. | Rerun on-board diagnostic at normal operating temperature. | Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE . |
| P1117 | ECT | ECT sensor or circuit signal intermittent. | PCM has detected an intermittent signal. | Incorrect EPC pressure, either high or low which will result in harsh or soft shift. | Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE . |
| P0117 | ECT | ECT indicates 125°C(254°F). | ECT temperature higher or lower than expected during KOEO and KOER. | Torque converter clutch will always be off, resulting in low fuel economy. | Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE . |
| P0118 | ECT | ECT indicates -40 °C (-40 °F). | ECT temperature higher or lower than expected during KOEO and KOER. | Torque converter clutch will always be off, resulting in low fuel economy. | Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE . |
| P0122, P0123, P1120 | TP | TP DTCs. | Powertrain control module has detected an error. This error may cause a transaxle concern. | Harsh engagements, firm shift feel, abnormal shift schedule, torque converter clutch does not engage. Torque converter clutch cycling. | Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE . |
| P0300-P0308, P0320, P0340, P1351-P1364 | EI | EI system. | EI system has a malfunction which may cause a transaxle concern. | Engine malfunction, no converter engagement. | Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE . |
| P0712 | TFT | 171 °C(340°F) indicated TFT sensor circuit grounded. | Voltage drop across TFT sensor exceeds scale set for temperature of 171°C (340°F). | Torque converter clutch and stabilized shift schedule may be enabled sooner after cold start. Harsh or soft shifts. May flash TCIL, KOEO, KOER. | Go To PINPOINT TEST B: TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR |
| P0713 | TFT | -43°C(-45°F) indicated TFT sensor circuit open. | Voltage drop across TFT sensor exceeds scale set for temperature -43°C (-45 °F). | Torque converter clutch and stabilized shift schedule may be enabled sooner after cold start. Harsh or soft shifts. May flash TCIL, KOEO, KOER. | Go To PINPOINT TEST B: TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR |
| P1711 | TFT | TFT out of onboard diagnostic range. | Transaxle not at operating (25°F-240°F) temperature during onboard diagnostic, KOEO, KOER. | Warm or cool vehicle to normal operating temperature. | Go To PINPOINT TEST B: TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR |
| P1713 | TFT | No change in TFT - low range. | PCM has detected no TFT change at low-range during operation. | May flash TCIL. | Go To PINPOINT TEST B: TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR |
| P1718 | TFT | No change in TFT - high range. | PCM has detected no TFT change at high-range during operation. | May flash TCIL. | Go To PINPOINT TEST B: TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR |
| P1783 | TFT | Transaxle overtemp condition indicated 149° C (300°F). | Fluid temperature exceeded 149°C (300° F). | Increase in EPC pressure during overtemp only. | Go To PINPOINT TEST B: TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
