V70 2.4 L5-2.4L VIN 61 B5244S (2001)
Oil temperature sensor
The temperature sensor is an NTC sensor. The temperature sensor is on the transmission control system inside the side cover. It gauges the
temperature of the transmission fluid in the oil pan. The temperature sensor is integrated in the cable harness. The temperature sensor is supplied with
5 V and is grounded via the transmission control module (TCM). The control module can determine the transmission fluid temperature by measuring
the voltage drop above the NTC resistance of the sensor. The control module stores the time the temperature has been within a certain temperature
range. If a certain temperature and time has been exceeded, a diagnostic trouble code (DTC) indicating that a oil change is necessary is stored.
There are diagnostics for the temperature sensor.
Gear-shift position sensor
The gear-shift position sensor is mounted on the top of the transmission housing, on the gear shift linkage rod. The gear selector contains a Park /
Neutral position (PNP) switch and connectors which inform the transmission control module (TCM) about which gear is selected and if the back-up
gear is selected so that the reversing lamps can be lit. The gear-shift position sensor is a position switch which is supplied via +15. A number of
trailing contacts supply power to the sensor outputs. The combination of pins A, B. C and PA indicate the current gear selector position (see the table
below). The trailing contacts can either be closed or open. There are diagnostics for the gear-shift position sensor.
Table for the gear-shift position sensor
The value indicates the position of the gear-shift position sensor (A, B. C and PA), see the table.
= High signal (open)
- = Low signal (grounded)
