P0700 – Transmission Control System Malfunction

This code indicates that the transmission control module (TCM) has detected a malfunction in the transmission control system. The TCM may have detected a problem with the transmission sensors, solenoids, or other components.

P0701 – Transmission Range Sensor Circuit Malfunction

This code indicates that the transmission range sensor (TRS) is not sending the correct signal to the TCM. The TRS is responsible for telling the TCM what gear the transmission is in.

P0702 – Transmission Range Switch Circuit Malfunction

This code indicates that the transmission range switch (TRS) is not making proper contact with the TCM. The TRS is responsible for telling the TCM what gear the transmission is in.

P0703 – Transmission Input Speed Sensor Circuit Malfunction

This code indicates that the transmission input speed sensor (ISS) is not sending the correct signal to the TCM. The ISS is responsible for telling the TCM how fast the transmission input shaft is rotating.

P0704 – Transmission Output Speed Sensor Circuit Malfunction

This code indicates that the transmission output speed sensor (OSS) is not sending the correct signal to the TCM. The OSS is responsible for telling the TCM how fast the transmission output shaft is rotating.

P0705 – Transmission Throttle Position Sensor Circuit Malfunction

This code indicates that the transmission throttle position sensor (TPS) is not sending the correct signal to the TCM. The TPS is responsible for telling the TCM how far the accelerator pedal is pressed.

P0706 – Transmission Kickdown Switch Circuit Malfunction

This code indicates that the transmission kickdown switch is not making proper contact with the TCM. The kickdown switch is responsible for telling the TCM to downshift the transmission.

P0707 – Transmission Neutral Switch Circuit Malfunction

This code indicates that the transmission neutral switch is not making proper contact with the TCM. The neutral switch is responsible for telling the TCM that the transmission is in neutral.

P0708 – Transmission Overdrive Switch Circuit Malfunction

This code indicates that the transmission overdrive switch is not making proper contact with the TCM. The overdrive switch is responsible for telling the TCM to turn on the transmission overdrive.

P0709 – Transmission Shift Solenoid A Circuit Malfunction

This code indicates that the transmission shift solenoid A is not working properly. The shift solenoid A is responsible for shifting the transmission into first gear.

P0710 – Transmission Shift Solenoid B Circuit Malfunction

This code indicates that the transmission shift solenoid B is not working properly. The shift solenoid B is responsible for shifting the transmission into second gear.

P0711 – Transmission Shift Solenoid C Circuit Malfunction

This code indicates that the transmission shift solenoid C is not working properly. The shift solenoid C is responsible for shifting the transmission into third gear.

P0712 – Transmission Shift Solenoid D Circuit Malfunction

This code indicates that the transmission shift solenoid D is not working properly. The shift solenoid D is responsible for shifting the transmission into fourth gear.

P0713 – Transmission Shift Solenoid E Circuit Malfunction

This code indicates that the transmission shift solenoid E is not working properly. The shift solenoid E is responsible for shifting the transmission into fifth gear.

P0714 – Transmission Shift Solenoid F Circuit Malfunction

This code indicates that the transmission shift solenoid F is not working properly. The shift solenoid F is responsible for shifting the transmission into sixth gear.

P0715 – Transmission Shift Solenoid G Circuit Malfunction

This code indicates that the transmission shift solenoid G is not working properly. The shift solenoid G is responsible for shifting the transmission into reverse gear.

P0716 – Transmission Fluid Pressure Sensor Circuit Malfunction

This code indicates that the transmission fluid pressure sensor is not sending the correct signal to the TCM. The transmission fluid pressure sensor is responsible for telling the TCM the pressure of the transmission fluid.

P0717 – Transmission Input Speed Sensor Circuit Intermittent

This code indicates that the transmission input speed sensor (ISS) is sending an intermittent signal to the TCM. The ISS is responsible for telling the TCM how fast the transmission input shaft is rotating.

P0718 – Transmission Output Speed Sensor Circuit Intermittent

This code indicates that the transmission output speed sensor (OSS) is sending an intermittent signal to the TCM. The OSS is responsible for telling the TCM how fast the transmission output shaft is rotating.

P0719 – Transmission Throttle Position Sensor Circuit Intermittent

This code indicates that the transmission throttle position sensor (TPS) is sending an intermittent signal to the TCM. The TPS is responsible for telling the TCM how far the accelerator pedal is pressed.

P0720 – Transmission Kickdown Switch Circuit Intermittent

This code indicates that the transmission kickdown switch is making intermittent contact with the TCM. The kickdown switch is responsible for telling the TCM to downshift the transmission.
