How To Fix Oxygen Sensor On A Malibu 2021

P0132 Chevy Malibu

P0132 is a common OBDII lawmaking that occurs in many vehicles, including theChevy Malibu. The code is triggered when:

The voltage at the sensor remains higher up threshold for xx seconds or more.
The air fuel sensor stays in rich biased mode for besides long.

There are as well some less probable problems that can cause P0132. Nosotros'll become over those beneath.

When the Malibu has depression O2 sensor voltage at B1S1, it'll trigger P0131.

Chevy Malibu P0132 Symptoms

Typically, the only symptom of P0132 is going to be the service engine soon light. In some cases, there tin can exist other symptoms likewise. These symptoms include:

They are relatively affordable at Autozone or Amazon.
Wiring Harness Issues– The wiring that goes to the front and rear oxygen sensors is very susceptible to damage. This is due to the fact that O2 sensors are under the chassis where they are subject to punishment from route debris, and they are subjected to a lot of exhaust heat. The downstream sensor is especially susceptible to this trouble Here's how to notice a brusk in the wiring harness (Youtube).
Harm to the Terminal– The terminal that the oxygen sensor connects to (the plug) is also relatively susceptible to impairment. You'll want to make sure that there is voltage going to information technology. There's more on that directly below.

If yous don't have admission to a multimeter, it certainly wouldn't hurt to cheque the wiring to between the fuse box and the Oxygen sensor offset. If it ends up being a wiring issue, it'll salvage you money over buying an unnecessary O2 sensor.

You tin also use a voltage test lite to determine whether or non the oxygen sensor is getting whatsoever voltage at all (they're about $5 at Walmart).

If it's non getting any voltage, attach the examination low-cal to the harness plug and shake the wiring a little bit. If the calorie-free comes on, even for a second, you know that you have a brusk circuit causing the P0132 trouble code.
