P207A Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit (Bank 2)

Unspecified circuit failure of the position feedback on the bank 2 tuning valve. It presupposes a second, separately sensed valve, which in practice means a V-engine with one switchable flap per bank. Nobody publishes this code: the GM tables use a single sensed valve (P2076 to P2078), and in Ford's literature only the runner control flaps (IMRC, P2004 onward) are monitored bank by bank. Following CARB, the controller still has to detect an open or shorted input even if it does not tell those cases apart. Because the bank 2 sensor usually sits at the rear of the manifold, chafed wiring under the cowl is worth checking first; for a pure bank 1 fault see P2075, for refined bank 2 fault types P207C and P207D.

Likely causes

Symptoms

• Check engine light (manufacturer-dependent)
• Mostly no change in driving behaviour

Repair estimate

Typical range across vehicles; the real cost depends on what the testing finds.
