DTC P0998:00 [Aw6A-El]: Notes

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0998:00	Shift solenoid F circuit malfunction (short to GND/open circuit)
DETECTION CONDITION	Open or short circuit in shift solenoid F signal system (The solenoid circuit current value input to the TCM is continuously less than 23 mA for 100 ms or more). Diagnostic support note: The MIL illuminates if the TCM detects the above malfunction condition during the first drive cycle. The AT warning light illuminates if the TCM detects the above malfunction condition during the first drive cycle. PENDING CODE is not available. FREEZE FRAME DATA is available. The DTC is stored in the TCM memory.
POSSIBLE CAUSE	Coupler component connector or terminal malfunction Short to GND in wiring harness between shift solenoid F terminal B and TCM terminal B21 Short to GND in wiring harness between shift solenoid F terminal A and TCM terminal B16 Shift solenoid F connector or terminal malfunction Shift solenoid F malfunction Open circuit between shift solenoid F terminal B and TCM terminal B21 Open circuit between shift solenoid F terminal A and TCM terminal B16 TCM malfunction
