Not sure where I got this:

Fault code, OBD II (TestBook) Fault description Effect Warning lamp illumination
MIL Sport/Manual
P0705 (14, 23) * Gear position switch, incorrect outputs Maintains current gear in low range, limp home mode in high range. Shift pressure to maximum, harsh gear shifts/engagement. On On

P0741 (5) * Torque converter lock-up clutch fault May affect driveability On Off
P0743 (7, 25) * Torque converter lock-up solenoid (MV 3), open or short circuit Limp home mode in low and high ranges. Shift pressure to maximum, harsh gear shifts/engagement. On On
P0748 (10, 28) * Pressure regulating solenoid (MV 4), open or short circuit Limp home mode in low and high ranges. Shift pressure to maximum, harsh gear shifts/engagement. On On
P0753 (8, 26) * Shift solenoid (MV 1), open or short circuit Limp home mode in low and high ranges. Shift pressure to maximum, harsh gear shifts/engagement. On On
P0758 (9, 27) * Shift solenoid (MV 2), open or short circuit Limp home mode in low and high ranges. Shift pressure to maximum, harsh gear shifts/engagement. On On
P1562 (24) * Battery supply below 9V while engine running Maintains current gear in low range, limp home mode in range. Shift pressure to maximum, harsh gear shifts/engagement. Off On
P1601 (4) * ECU, EEPROM checksum Limp home mode in low and high ranges. Shift pressure to maximum, harsh gear shifts/engagement. On On
P1606 (3) * EEPROM No apparent effect On† Off
P1606 (6) * Watchdog No apparent effect On On
P1612 (2) * Solenoid valves power supply relay, sticking closed or open circuit Limp home mode in low and high ranges. Shift pressure to maximum, harsh gear shifts/engagement. On On
P1613 (1) * Solenoid valves power supply relay, sticking open or short circuit Limp home mode in low and high ranges. Shift pressure to maximum, harsh gear shifts/engagement. On On
P1705 (39) Transmission high/low range, implausible input No apparent effect On Off
P1810 (12, 13) Sport/Manual warning lamp circuit fault Lamp fails bulb check or is permanently illuminated. No effect on gearbox operation. On Off
P1841 (16) * CAN bus fault Maintains current gear in low range, limp home mode in high range. Shift pressure to maximum, harsh gear shifts/engagement. On On
P1842 (15) * CAN level monitoring Maintains current gear in low range, limp home mode in range. Shift pressure to maximum, harsh gear shifts/engagement. On On
P1843 (17) * CAN time-out monitoring Maintains current gear in low range, limp home mode in high range. Shift pressure to maximum, harsh gear shifts/engagement. On On
P1884 (11) * CAN message: Engine friction invalid No apparent effect. On Off
P1884 (18) * CAN message: Throttle position invalid Substitute throttle angle of 50% adopted. No kickdown. Operates in economy modes only. On On
P1884 (19) CAN message: Engine temperature invalid Substitute engine temperature derived from other inputs. No apparent effect. On Off
P1884 (20) CAN message: Road speed invalid No apparent effect On Off
P1884 (33, 34) * CAN message: Engine torque invalid Substitute engine torque of derived from other inputs. May affect shift quality. On Off
P1884 (35) * CAN message: Engine speed invalid Maintains current gear in low range, limp home mode in high range. Shift pressure to maximum, harsh gear shifts/engagement. On On
P1884 (37) CAN message: Engine air intake temperature invalid No apparent effect. On Off
P1844 (38) Altitude shift control invalid No reduced torque compensation, possible reduction in performance/ driveability at altitude or high ambient temperatures. On Off
* = Emissions (OBD II) relevant
On† = MIL illuminates immediately (in all other faults, MIL On = illuminates in the 2nd consecutive drive cycle if fault still present)
