DTC P07C0 Input/Turbine Speed Sensor "A" Circuit High


DESCRIPTION

The transmission revolution sensor (NT) detects the input shaft rotation speed and sends it to the TCM.
Based on the transmission revolution sensor (NT) signal and the transmission revolution sensor (SP2) signals, the TCM controls engine torque and shift timing. Based on the input shaft rotation speed and the engine speed signal, lock-up control is performed.

DTC No.

  2. Transmission revolution sensor (NT) input voltage is higher than 2.6637 V.
  3. 0.5 seconds
  4. 1-trip detection logic

MONITOR DESCRIPTION

The transmission revolution sensor (NT) detects the input shaft speed. The TCM calculates gear shifts comparing the transmission revolution sensor (NT) with the transmission revolution sensor (SP2).
If the TCM detects no signal from the transmission revolution sensor (NT) even while the vehicle is moving, it will conclude that is a malfunction of the transmission revolution sensor (NT). The TCM will illuminate the MIL and store a DTC.

INSPECTION PROCEDURE

NOTICE:
Perform registration and/or initialization when parts related to the automatic transmission are replaced (Click here).
HINT:
After performing repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
  1. Perform the D Position Shift Test inspection in Road Test (Click here).
  2. Check for DTCs again (Click here).

DATA LIST
NOTICE:
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
HINT:
Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
  1. Warm up the engine.

  2. Turn the engine switch off.

  3. Connect the GTS to the DLC3.

  4. Turn the engine switch on (IG).

  5. Turn the GTS on.

  6. Enter the following menus: Powertrain / ECT / Data List / SPD (NT).

  7. According to the display on the GTS, read the Data List.

    2. Nearly equal to engine speed: Lock-up off (idling with shift lever in N)
    Data is displayed in increments of 50 rpm.
    HINT:
    1. SPD (NT) is always 0 while driving: Open or short in the sensor or circuit.
    2. SPD (NT) is always more than 0 and less than 300 rpm while driving the vehicle at 50 km/h (31 mph) or more: Sensor malfunction, improper installation, or intermittent connection malfunction in the circuit.
