Atmospheric Pressure Greater
P0106 Than The Maximum or Less
Than The Minimum
3. 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.
Initial Inspection
Step 1
Next
Step 2 Check whether there is control system DTC code other than DTC P0068 P0106.
No
Check scan tool atmospheric pressure data.
Step 3
1. Engine Running
2. No intake air pressure sensor,
coolant temperature sensor, ETC
throttle position sensor, fuel injector,
ignition coil and misfire fault,etc.
3. Coolant temperature is higher than
60°C (140 ºF).
4. Duration Longer Than 15 s
Check the existence of the following conditions:
(a) Damaged Intake Manifold Pressure / Temperature Sensor
Housing Is, Broken Vacuum Tubes
(b) Damaged Intake Manifold Pressure / Temperature Sensor
Seals
(c) Intake Manifold Pressure / Temperature Sensor Loose or
Improperly Installed
(d) Throttle seals is damaged, causing air leaks.
(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.
Results:
DTC P0068 P0106
DTC Code Other Than DTC P0068 P0106
Yes
(a) Compare the actual atmospheric pressure with atmospheric
pressure parameter. Refer to "4G18-D Engine Control
Control System JL4G15-D
