Code result

P0152

O2 Sensor Circuit High Voltage

Moderate severity

What it means

Same condition as P0132 but on bank 2. The upstream sensor reports a continuously rich condition or has a short to supply voltage.

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

  • Bank 2 running rich (leaking injector, high fuel pressure)

    high

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

  • Signal wire shorted to supply voltage

    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.
