- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Pressure control solenoids are current-controlled proportional valves, and what B and C mean depends on the design: on GM's clutch-to-clutch automatics they are the pressure valves of clutches 2 and 3, on GM's CVT B is primary pulley pressure and C line pressure, on Jatco CVTs B is the secondary pressure valve, on Saab's AF40 B and C are clutch valves SLC1/SLC2. P0775 is the general code for valve B. No manufacturer document available to us uses it; the trade journal MOTOR names it as a performance code of line pressure valve B on Ford's 5R55, set together with ratio codes after a broken overdrive servo. Sub-codes for performance, stuck on, electrical and intermittent follow (P0776–P0779).
