See step  2

1. According to the display on the GTS, read the Data List.

   Powertrain > Engine > Data List 

   Tester Display
   Atmospheric Pressure
   Boost Pressure Sensor

   Result

   Result	Proceed to
   Difference between Atmospheric Pressure and Boost Pressure Sensor is higher than 13 kPa (1.89 psi)	A
   Other than above	B

Result: 

B 

See step  7

Result: 

A 

See step  3

1. Check the value of Data List item.

   Powertrain > Engine > Data List 

   Tester Display
   Atmospheric Pressure
   Boost Pressure Sensor

2. Using the following table, determine the normal atmospheric pressure for the current altitude and temperature.

   HINT: 

   • Standard atmospheric pressure is approximately 101 kPa (abs) (14.65 psi (abs)).
   • For every 100 m (328 ft.) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.15 psi). This varies depending on the weather.
3. Compare the values of Atmospheric Pressure and Boost Pressure Sensor with the normal atmospheric pressure in the table.

   Result

   Result	Proceed to
   Difference between (difference between value of Boost Pressure Sensor and normal atmospheric pressure) and (difference between value of Atmospheric Pressure and normal atmospheric pressure) is 4 kPa (0.58 psi) or higher	A
   Other than above	B

   HINT: 

   • Use the table below for reference only.
   • In Example 1, as the pressure difference is 4 kPa (0.58 psi) or higher, proceed to the next step.
   • In Example 2, as the pressure difference is less than 4 kPa (0.58 psi), replace the ECM.

   Item	Example 1			Example 2
   	Atmospheric pressure	Difference between measured value and normal atmospheric pressure	Difference between (difference between value of Boost Pressure Sensor and normal atmospheric pressure) and (difference between value of Atmospheric Pressure and normal atmospheric pressure)	Atmospheric pressure	Difference between measured value and normal atmospheric pressure	Difference between (difference between value of Boost Pressure Sensor and normal atmospheric pressure) and (difference between value of Atmospheric Pressure and normal atmospheric pressure)
   Normal atmospheric pressure	100 kPa (abs) (14.5 psi (abs))	-	6 kPa (0.87 psi)	100 kPa (abs) (14.5 psi (abs))	-	2 kPa (0.29 psi)
   Boost Pressure Sensor in the Data List	110 kPa (abs) (15.95 psi (abs))	10 kPa (1.45 psi)		108 kPa (abs) (15.66 psi (abs))	8 kPa (1.16 psi)
   Atmospheric Pressure in the Data List	96 kPa (abs) (13.92 psi (abs))	4 kPa (0.58 psi)		94 kPa (abs) (13.63 psi (abs))	6 kPa (0.87 psi)
