Ford Galaxy / Ford S-MAX. Manual — part 513

On vehicles with auto start/stop function, information is required about whether a gear is
engaged or the transmission is in neutral. The neutral position sensor is located on the
transmission housing for this purpose. This is connected to the shift linkage by an additional
linkage on the transmission.

The neutral position sensor is a Hall sensor and is supplied with 5 Volt by the PCM. The
signal voltage varies between 0.5 and 5 Volt when operating the linkage and is monitored
by the PCM.

A fixed voltage value is stored in the PCM for each gear. All values lying between those for
the individual gears are stored as values for the neutral position. The PCM therefore always
detects whether or not a gear is engaged.

After replacing the sensor, the value from the old sensor is reset in the PCM using IDS. The
vehicle must then be driven a certain distance so that the PCM can learn the new values for
the relevant gears and neutral positions.

To do this, the vehicle must be driven a total of 5 times for 10 seconds each, alternately in
3rd and 4th gear with low acceleration.

NOTE: If a fault occurs on the neutral position sensor when the engine is stationary, the
vehicle can still be started with the ignition key. In this case, a corresponding DTC is set
in the PCM.

General Procedures

1.

NOTE: Establish the cause of the damage
and resolve it.

Check whether the bearing cage is
damaged at the top, side or at the
openings due to unprofessional use of a
special tool or use of the wrong tool.
Install a new bearing if necessary.

2.

Check whether the ends of the taper
rollers are discolored as a result of
inadequate lubrication or overheating,
possibly through excessive pre-load.
Install a new bearing and new seals if
necessary.
Check the bearing is correctly lubricated.

3.

Check whether the ends of the taper
rollers are worn away due to incorrect
installation, excessive pre-load or faulty
bearing seating.
Install a new bearing and new seals if
necessary.
Check the bearing is correctly lubricated.

4.

Check whether the bearing surfaces are
gray or gray/black with deposits between
the rollers.
Install a new bearing and new seals if
necessary.
Check the bearing is correctly lubricated.

5.

Check whether the bearing ring surfaces
are grooved caused by static impact.
Install a new bearing if its surface is
rough, or if it is noisy.

6.

NOTE: Overheating can cause loss of surface
hardness.

Check for a dark blue colors caused by
overheating (yellow or brown is normal)
due to excessive pre-load or inadequate
lubrication.
Install a new bearing, new seals and check
other components as necessary.

7.

Check the surfaces for abrasion due to
metal fatigue.
Install a new bearing and clean all other
affected components as necessary.
