Replacing MAP Sensor
If the difference between the pressures is greater than 140 hPa, try replacing the boost pressure sensor according to Manifold absolute pressure (MAP) sensor, replacing .
HINT: Normal atmospheric pressure is 1013 hPa. Check which of the sensors appears to display the incorrect reading.
If the fault is not in the boost pressure sensor, replace the engine control module (ECM) according to Engine control module (ECM), replacing .
The atmospheric pressure sensor is built into the engine control module (ECM) and therefore cannot be replaced as a separate item.
A new engine control module (ECM) is delivered without software. For the engine control module (ECM) to function after replacement the engine control module (ECM) must be programmed.
Remedy as necessary.
