P2875Clutch B Engagement Time Performance/Too Slow
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2875 tells that clutch B takes too long to grip once the control unit has asked for it. Slow filling leaves a gap in drive during shifts into the gears served by clutch B, with a flare of engine speed before the clutch finally holds. No manufacturer explains P2875 in a public document; the requirement for functional monitoring comes from CARB 13 CCR 1968.2. Comparable timing logic is visible in Volvo's rear-axle clutch, which reports slow coupling as P286D00, and in Mitsubishi's Mirage CVT, which waits 2 s for the second auxiliary ratio before flagging P2858. Typical root causes are low or aerated fluid, a partly blocked filter or valve passage, worn seals that leak during fill, or an actuator motor that has lost speed.
