Input/Turbine Speed Sensor "A" No Signal

DESCRIPTION

The transmission revolution sensor (NT) detects the input shaft rotation speed and sends it to the ECM.

Based on the transmission revolution sensor (NT) signal and the transmission revolution sensor (NC) signals, the ECM controls engine torque and shift timing. Based on the input shaft rotation speed and the engine speed signal, lock-up control is performed.

MONITOR DESCRIPTION

The NT terminal of the ECM detects a pulse signal from the transmission revolution sensor (NT) (input RPM). The ECM calculates gear shifts by comparing input signals of the transmission revolution sensor (NT) with the transmission revolution sensor (NC).

While the vehicle is being driven in 1st, 2nd, 3rd, 4th, 5th, 6th, 7th or 8th gear with the shift lever in D, if the input shaft revolution (speed) is less than 300 rpm* when the vehicle speed is 22 km/h (14 mph) or more, the ECM interprets this as a malfunction, illuminates the MIL and stores a DTC.

*: Pulse is not output or is irregularly output.

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 Techstream 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.

(a) Warm up the engine.

(b) Turn the ignition switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / Transmission / Data List / NT Sensor Speed.

(g) Read the Data List according to the display on the Techstream.
