P2316 means the coil F control line, cylinder 6, sits at a voltage it should not have while the module switches it – a short to supply or a fault inside the coil. In VW's 2014 Touareg tables the high threshold is a signal voltage above about 5.1–7.0 V. GM's 2019 table for the supercharged LT5 V8 in the Corvette checks the line with the driver switched on, accepts it only if no path below 100 ohms to supply exists, and rates the result Type B: 50 failed checks in 63 and two trips before the MIL comes on. Saab's 9-5 2.8 V6 sets P2316 after 4 s or 30 s in total within 400–5,000 rpm, and notes that the ignition coil could also log misfire P0300 or P0306. If the fault is intermittent, wiggling the harness while watching the cylinder 6 misfire counter helps find it.

Likely causes

Coil F control wire shorted to a supply line
Internal short in coil F
Intermittent contact in the harness near coil F
Engine module driver defective

Symptoms

  • Check engine light on
  • Misfire on cylinder 6, P0306 may also be stored
  • Intermittent stumbling
