Without powerful electronic management systems, we might as well be back in the performance equivalent of the Stone Age, rubbing sticks together trying to make fire and belting things with rocks.
As a general rule, most electronic components fitted to the Subaru WRX have proved to be extremely reliable in service, with one notable exception.
The air mass sensor calculates the actual weight of incoming intake charge and is a major determining parameter used by the ECU to calculate both injection time and ignition advance. Flash 02 and later equipped air mass sensors feature an in-built air temperature sensor that further improves sensor accuracy.
Air mass sensors fitted to the Subaru WRX Version V and VI cars are a bit on the fragile side, especially when used with aftermarket airfilters. This type of air mass sensor uses a “hot film” sensing element.
The Subaru ECU monitors the amount of cooling effect air has passing by the heated sensing surface, and from this datum can calculate with a high degree of accuracy the actual weight of the intake charge. Less desirable is the effect of contamination by particulates and oil residue can have on sensor operation.
The Subaru WRX can be sensitive, even small amounts of dust or oil can be enough to reduce sensor output by up to 30-50%, seriously compromising engine operation. Correct operation can sometimes be restored by carefully cleaning the sensor element with electronic contact cleaner. However, don’t use a contact lubricant, as this will make any sensor contamination issues worse.
Cleaning is not always successful, as these sensors do suffer cumulative damage. Professional repair workshops will make a special point of checking this part during routine servicing.
