P0997 Shift Solenoid F Control Circuit Range/Performance

Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modePossible

The drive circuit of shift solenoid F works electrically but its measured current or voltage does not fit the command. No manufacturer was found to document this code. The users of the F block, Nissan's RE0F11A CVT and a 2019 Mitsubishi six-speed, list only P0998 and P0999. FCA's nine-speed bulletin 21-019-17 (2015 Chrysler 200 and Jeep Cherokee) shows how the slot is used for solenoids 2 to 5, with P0975, P0978, P0981 and P0984 for control circuit performance, but stops before a sixth solenoid. Genesis reports an electrical fault of its solenoid F under P2709 instead. CARB requires transmission outputs to be checked for proper function. P097F is the open circuit, P0998/P0999 low and high.

Likely causes

Solenoid coil resistance out of specification
High-resistance connector or harness contact
Weak driver stage in the transmission control module

Symptoms

  • Warning light depending on calibration
  • Missing or harsh shifts into gears using this solenoid
