P2619 is set when the crankshaft position output line is held at supply voltage while the module's low-side driver is switched on and expects it to be pulled down. GM's 2014 hybrid ECM table treats an impedance of 0.5 ohm or less toward power as the fault and evaluates it like the low case: 40 failures in 50 samples every 100 ms, engine not cranking, relay voltage of 11 V or more, Type B with MIL after two trips. GM also carries the code in its 2011, 2012, 2016 and 2023 tables, and Mitsubishi lists it for the 2022 Outlander. The usual cause is insulation damage that lets the line touch a positive feed, less often a defective output stage in the module. The listening controller then receives a constant level rather than teeth and may limit operation.

Likely causes

Damaged insulation lets the output touch a positive feed
Low-side driver in the engine module failed open
Back-feed through a corroded connector

Symptoms

  • MIL on after two drive cycles
  • Receiving module reports implausible crank signal
  • Possible reduced power or start problems
