Pump B Control Circuit /OpenP2632 is a generic OBD-II powertrain diagnostic trouble code: Pump B Control Circuit /Open. It is logged by the engine control unit when the powertrain monitor detects that a specific fault threshold has been exceeded — typically resulting in the malfunction-indicator lamp (MIL / check-engine light) being illuminated.

Disabling P2632 in software
RaceTune can permanently disable P2632 — and any other OBD-II diagnostic trouble code — on every ECU family we support. The monitor is disabled inside the ECU itself, so the fault stops being logged: the warning light stays off and the engine never enters limp mode for this code. The change is tied to your exact software version.
