4) Installation notes
The sensor is designed for installation in the planes of an automobile engine intake manifold. Pressure pipe and
temperature sensor together out of the intake manifold, to realize the sealing of the atmosphere with a O ring. If
you take the right way to install to the car (extraction pressure, from the intake manifold pressure over sloped
down and so on), can not ensure the formation of condensed water pressure sensitive element. Drilling and fixed
on the intake manifold must be carried out in accordance with the supply, in order to ensure the long sealing and
erosion resistance of medium. Joint reliable electrical connection contact except mainly affected by components of
joint, but also with quality and size precision materials joints matched the wire harness. 6 bolt mounting torque is
8~10Nm
5) Fault phenomenon and judgment method
Fault phenomenon: poor idling flameout.
Common fault: 1, using the process of abnormal high pressure or reverse current; 2, the repair process of vacuum
element
Damage.
Repair note: impact to the vacuum unit using high pressure gas no repair process; find fault to replace the sensor
The time to check whether the generator output voltage and current of the normal.
A simple method to measure:
Temperature sensor:
(unloading joints) digital multimeter to Ohm, two probes are respectively connected sensor a#, b# pin, 20
℃ rated
resistance is 2500K Ω , resistance value other corresponding can amount by the above characteristic curve.
Measurement can also be used when the simulation method, in particular to send wind direction sensor with a hair
dryer (note not reliable too close), observe the change of the sensor resistance, the resistance should be reduced.
