5 Inspect the intake manifold pressure sensor. A. Shut down the engine. B. Turn the ignition switch to ON. C. Without disconnecting the intake manifold pressure sensor wiring harness connector, pull out the intake manifold pressure sensor from the intake manifold and use the vacuum pump. D. Apply 50 kPa pressure on the intake manifold pressure sensor. Observe whether the intake manifold pressure (MAP) sensor value changes?
6 Inspect the intake manifold pressure sensor installation port and vacuum tubes. A. Inspect the intake manifold pressure sensor installation port and vacuum tubes. Are the installation port and vacuum tubes blocked?
7 Inspect whether the intake manifold pressure sensor parameter responds to changes. A. Engine Running B. After changed throttle valve. Stuck throttle valve, look at air intake manifold pipe pressure sensor . Whether the sensor parameter value is rapidly changed according to the change of the position of Does intake manifold pressure (MAP) sensor value rapidly change with the throttle position
8 Inspect the intake manifold pressure sensor installation port and vacuum tubes. A. Inspect the intake manifold pressure sensor installation port and vacuum tubes. Are the installation port and vacuum tubes blocked?
9 Use fault diagnosis tester to confirm if DTC is stored again . A. Connect fault diagnosis tester to the data link connector. Yes Clean and service the intake manifold and No Replace the intake manifold pressure Yes Go to step 9 No No Replace the intake manifold pressure / Yes Yes Clean and service the intake manifold and No Go to step 9 163 |
