P062E Fuel Injector Driver Circuit Performance Bank 2

Direct-injection injectors (petrol and common-rail diesel) need a high boost voltage generated in the module to open fast; the module then holds them with pulsed battery voltage. P062E is the bank 2 counterpart of P062D for V engines with separate driver circuits per bank. The only user found is Ford's 2023 diesel (6.7 L Power Stroke V8): the driver chip's internal logic reports a loss of the high-voltage supply and the code sets within 0.5 s; group supply faults of the injectors are P2150/P2151 and P2153/P2154. GM monitors the same boost voltage only under P062D. The injectors of bank 2 then open incorrectly – misfires on one side of the engine, rough idle, loss of power and possibly limp mode. Check wiring and connectors under the bank 2 valve cover and each injector for shorts before suspecting the engine module.

Likely causes

Short in an injector wire or injector of bank 2
Engine module or driver chip faulty internally
Connector or harness under the bank 2 valve cover
Undervoltage or poor ground

Symptoms

  • Check engine light on
  • Misfires on one side of the engine
  • Loss of power or limp mode
  • Rough idle, starting problems
