P210F Throttle Actuator B Control System - Forced Limited RPM

EmissionsRelevant

Drive cycleNot required

Limp modePossible

P210F is a status code for the second throttle: the controller has capped engine speed because control of throttle B is no longer reliable. No manufacturer documents this code publicly. Its bank 1 sibling P2110 is well described: in Ford's 2012 summary it follows the loss of both throttle position sensors or a fault found by the throttle plate controller, sets the MIL and wrench lamp and enforces an rpm limit with fuel and spark. P210F would play the same role on engines with two throttles; the root cause is stored as a separate code such as P210A, P210B or a throttle B sensor fault, and that is what gets repaired. CARB treats such fallback modes as malfunctions when they can raise emissions. Expect a hard rev limit.

Likely causes

Electrical or mechanical fault of throttle B (see companion code)

Loss of the position signals of throttle B

ECU software reacting too strictly

Symptoms

Engine will not rev past a fixed limit
Engine and wrench lamp on
