Electronic Control Module (ECM)
Comparison of each measured response time (lean and rich) to predetermined maximum map values which depends on engine speed and load. If sum (measured times) during 115 lambda controller cycles is > than sum (max. map values) a fault will be detected.
max. map values for lean and rich [ms]
