Code P1472 2016 GMC Sierra Description

Control modules connected to the serial data circuits monitor the communication during normal vehicle operation. Operating information and commands are exchanged among the control modules. Each module on the serial data circuit maintains a transmit error counter and a receive error counter. The counter values increase with detected errors and decrease with error-free messages. The Diagnostic Trouble Code (DTC) will be set when the Particulate Matter Sensor Signal Message Counter is Incorrect.

What are the common symptoms of the P1472 code in a 2016 GMC Sierra?

Symptoms include an illuminated check engine light, decreased fuel efficiency, possible engine performance issues, and the vehicle failing emissions tests.

What causes the P1472 code in a GMC Sierra?

Common causes include a faulty particulate matter sensor, wiring or connector issues, a malfunctioning control module, or software glitches in the engine control module (ECM).

Can I drive my 2016 GMC Sierra with the P1472 code?

While the vehicle may still be drivable, ignoring this code can lead to worsening emissions performance and potential damage to the exhaust system over time.

How do you diagnose the P1472 code?

Diagnosis typically involves scanning for codes, inspecting the particulate matter sensor and its wiring, checking for software updates, and testing the sensor's signal output.

What repairs are needed to fix the P1472 code?

Repairs may include replacing the particulate matter sensor, repairing damaged wiring or connectors, or updating/reprogramming the engine control module.

How much does it cost to fix the P1472 code on a GMC Sierra?
