4. Diagnostic Steps:
Note
Before carrying out this diagnosis step, observe the data list on scan tool and analyze the accuracy of the data, as
these will help with quick diagnosis.
Step 1
Initial Inspection
Check the existence of the following conditions:
(a)
Sensor housing damage, vacuum tubes broken.
(b)
Sensor seal damage.
(c)
Sensor loose or improperly installed.
(d)
Sensor tube blockage.
Next
Note
It is prohibited Connect intake manifold absolute pressure sensor 5 V reference voltage circuit to other components,
otherwise it will damage the sensor and ECM.
Step 2
Measure intake manifold absolute pressure sensor 5 V reference voltage.
