P2670

Actuator Supply Voltage B Circuit Low

Moderate severity

What it means

The supply voltage to actuator group B (e.g. solenoids, valves driven by ECU) is below the calibrated threshold. The affected actuators may be slow or unable to switch.

Is it safe to drive?

Use caution

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.

Most likely causes

  • Faulty supply relay

    high

    One of the most commonly reported causes for this code — check this first.

  • Wire shorted to ground

    medium

    A plausible cause — test and verify before replacing parts.

  • Connector pins corroded - high contact resistance

    low

    Less common, but worth ruling out after the more likely causes.
