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
Check there are no other control system DTC codes.
(a)
Connect scan tool to the datalink connector.
(b)
Turn the ignition switch to "ON" position.
(c)
Press the scan tool power button.
(d)
Select the following menu items: Engine/Read DTC codes.
(e)
Read DTC codes.
Are there DTC codes other than P0170, P0171, P0172, P2177,
P2178, P2187, P2188?
Yes
No
Step 2
Read the intake manifold absolute pressure sensor data.
(a)
Turn ignition switch to "OFF" position, connect scan tool.
(b)
Start the vehicle.
(c)
Read the intake manifold absolute pressure sensor data.
(d)
Read the scan tool for atmospheric pressure value, and
compare it with table
.
Is scan tool atmospheric pressure reading normal?
No
