Code Definition

P216E — Fuel Injector Group ‘F’ Supply Voltage Circuit Low

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Holden

About P216E

P216E is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Holden vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P216E is stored, the module has detected a signal or supply voltage lower than the expected operating range.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P216E is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Engine Control Module (ECM) monitors the battery voltage supplied to fuel injector group F to confirm the injectors have enough voltage to operate correctly. DTC P216E is set when the ECM detects that the injector group F supply voltage stays below the calibrated minimum for a set period while those injectors are expected to fire. A low supply usually means excessive voltage drop, high resistance, or a partial short to ground somewhere in the power feed to that group. The cylinders in group F may misfire or cut out, so the engine can run rough, lose power, and be hard to start, with the ma...
