Fault ID 293
Fault
Deck Pressure discrepancy fault
Description
This fault indicates primary channel and secondary channel deck pressure values differ by
Root Cause more than the calibrated maximum threshold. The fault will become inactive if the two
values converge below the maximum threshold.
1. Are there any active deck pressure 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 294
Fault
CIP discrepancy fault
Description
This fault indicates primary channel and secondary channel CIP pressure values differ by
more than the calibrated maximum threshold. The fault will become inactive if the two
Root Cause
values converge below the maximum threshold.
1. Are there any active CIP 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 295
Fault
TPS discrepancy fault
Description
This fault indicates primary channel and secondary channel TPS values differ by more
Root Cause than the calibrated maximum threshold. The fault will become inactive if the two values
converge below the maximum threshold.
1. Are there any active TPSsensor 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 296
Fault
TIT crosscheck fault
Description
This fault indicates the combined and inferred turbine inlet temperature differ by more
Root Cause than a calibrated maximum threshold. The fault will become inactive if the combined and
inferred turbine inlet temperatures converge
1. Are there any active TIT 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.
