TEO-540-C1A Engine Maintenance Manual
Fault ID 297
Fault
Manifold Temperature crosscheck fault
Description
This fault indicates the combined and inferred manifold temperature differ by more than a
Root Cause calibrated maximum threshold. The fault will become inactive if the combined and
inferred values converge
1. Are there any active MAT sensor slew rate, circuit or range faults? If yes, refer to troubleshooting
section for the active fault. If no, go to step 2.
2. Contact Lycoming Engines.
Fault ID 298
Fault
Deck Temperature crosscheck fault
Description
This fault indicates the combined and inferred deck temperature differ by more than a
Root Cause calibrated maximum threshold. The fault will become inactive if the combined and
inferred values converge
1. Are there any active deck temperature sensor slew rate, circuit or range faults? If yes, refer to
troubleshooting section for the active fault. If no, go to step 2.
2. Contact Lycoming Engines.
Fault ID 299
Fault
Manifold Pressure crosscheck fault
Description
This fault indicates the combined and inferred manifold pressure from throttle position
Root Cause differ by more than a calibrated maximum threshold. The fault will become inactive if the
combined and inferred values converge
1. Are there any active MAP sensor slew rate, circuit or range faults? If yes, refer to troubleshooting
section for the active fault. If no, go to step 2.
2. Contact Lycoming Engines.
Fault ID 300
Fault
Air mass flow crosscheck fault
Description
This fault indicates the primary and secondary air mass flow differ by more than a
Root Cause calibrated maximum threshold. The fault will become inactive if the primary and
secondary air mass flow rates converge
1. Are there any active venturi, CIP, or MAP sensor slew rate, circuit or range faults? If yes, refer to
troubleshooting section for the active fault. If no, go to step 2.
2. Contact Lycoming Engines.
