ON-VEHICLE INSPECTION

PROCEDURE

1. CHECK MANIFOLD ABSOLUTE PRESSURE SENSOR FUNCTION

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine and ECT / Data List / MAP.

(e) Read the values displayed on the Techstream.

Standard Condition:

80 to 110 kPa (0.8 to 1.1 kgf/cm2, 12 to 16 psi)

(f) Using the vacuum pump, measure the manifold absolute pressure sensor when a pressure of 67 kPa (503 mmHg, 19.8 in.Hg) is applied to the manifold absolute pressure sensor.

Standard Condition:

23 to 38 kPa (173 to 285 mmHg, 6.79 to 11.2 in.Hg)
