P2616 Camshaft A Position Signal Output Circuit High (Bank 1)

P2616 is the opposite fault to P2615: the outgoing camshaft A position line on bank 1 stays at supply potential although the module has switched its low-side driver on and wants the line low. In GM's 2018 CT6 tables the ECM declares a power short once the impedance toward the supply is 0.5 ohm or less, using the same window of 40 bad readings in 50 at 100 ms intervals, engine not cranking and at least 11 V; the code is Type C, so the warning lamp stays off. A chafed wire touching a battery feed or a failed output stage are the usual suspects. Mitsubishi also lists P2616 for the 2022 Outlander. The downstream controller sees a steady level instead of pulses, which can upset cam phasing or starting.

Likely causes

Output wire shorted to a battery or ignition feed
Low-side driver in the engine module no longer switching
Back-feed through a damaged or corroded connector

Symptoms

  • Stored code without warning lamp
  • Hard starting or hesitation after start
  • Cam phasing faults logged by the receiving module
