Description
Barometric Pressure Sensor (BPS) is a speed-density type
sensor and is installed on the air cleaner assemby. It senses absolute
pressure of the air cleaner assemby and transfers the analog signal
proportional to the pressure to the ECM.
Replacement
1.
Remove the condenser, and then remove the bottom cap (B) with L wrench (A) from the condenser.
Tightening torque :
9.8~14.7N.m (1.0~1.5kgf.m, 7.2~10.8 lb-ft)
2.
Remove the desiccant (A) from condenser using a long nose plier.
Inspection
1.
Ignition "ON"
2.
Using the scan tool.
3.
Emit intensive light toward photo sensor using a lamp, and check the output voltage change.
4.
The voltage will rise with higher intensive light and reduce with lower intensive light.
