P216E marks the feed of injector group F, the cylinder 6 injector on GM petrol direct injection, as shorted toward ground. It therefore concerns GM V6 and V8 engines with direct injection. The 2016 3.6 LGX and the 2018 LT4 tables use a current test: with the driver on, 25 A or more through the high side counts as a short, and 10 failures in 20 samples taken every 100 ms at 11 V or more store a type A code with the MIL on the first trip. GM's PI0631H for the 2012 and 2013 Impala includes P216E among the circuits that a harness rubbing on the transmission can damage; GM adds that usually only one circuit is hit. Diagnosis compares the resistance from the injector 6 feed pin to ground with the module unplugged. P216F is the high fault.

Likely causes

Cylinder 6 feed wire chafed through to ground
Cylinder 6 injector shorted to ground
Engine control module output stage faulty

Symptoms

  • Check engine lamp on immediately
  • Cylinder 6 misfire and loss of power
