P1488 2016 Chevrolet Silverado Code - Particulate Matter Sensor Protection Tube Performance
Quick Answer
The Particulate Matter (PM) sensor monitors the amount of the particulates (soot) in the diesel exhaust gas exiting the tailpipe. Common causes include Faulty Exhaust Particulate Matter Sensor, Exhaust Particulate Matter Sensor harness is open or shorted, Exhaust Particulate Matter Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1488 2016 Chevrolet Silverado Description
The operation of the PM Sensor is based on the electrical conductivity characteristic of the diesel particulate. As the exhaust gas flows over the sensing element, soot is absorbed in the combs between the electrodes, eventually creating a conductive path. When the path is formed, it generates a current based on the voltage being applied to the element. The measurement process continues until a preset current value is reached. To avoid misleading readings, the sensor performs a regeneration where the soot is cleaned off by heating up the element before the measurement phase begins. The amount of regenerations is based on vehicle strategy; when the calibrated number of regenerations is reached, the cumulative current readings are used to determine the amount of soot concentration in the exhaust gas which in turn determines the collection efficiency of the Diesel Particulate Filter (DPF).
The Diagnostic Trouble Code (DTC) will be set when the particular matter sensor control unit detects a fault in the particulate matter sensor circuitry.
What are the Possible Causes of the DTC P1488 2016 Chevrolet Silverado?
- Faulty Exhaust Particulate Matter Sensor
- Exhaust Particulate Matter Sensor harness is open or shorted

Common causes include debris or soot buildup in the particulate matter sensor protection tube, a damaged or faulty sensor, or exhaust system leaks.
4. Can a dirty particulate matter sensor cause code P1488?
Yes, excessive soot or debris on the sensor or within the protection tube can trigger this code.
5. How is code P1488 diagnosed in a 2016 Chevrolet Silverado?
A mechanic will inspect the particulate matter sensor and protection tube for damage or buildup, check for exhaust leaks, and use a scan tool to monitor sensor performance.
6. Can I drive my 2016 Chevrolet Silverado with a P1488 code?
Driving with this code is not recommended as it can lead to increased emissions and potential damage to the exhaust system over time.
7. How do you fix code P1488 on a 2016 Chevrolet Silverado?
Repairs may include cleaning or replacing the particulate matter sensor, clearing debris from the protection tube, or repairing any exhaust leaks.
8. How much does it cost to repair a P1488 code on a 2016 Chevrolet Silverado?
The repair cost can vary, but cleaning or replacing the sensor generally ranges from $200 to $600, depending on labor and parts.
9. Can exhaust system modifications cause the P1488 code?
Yes, modifications that affect exhaust flow or sensor placement can trigger this code.
10. Will clearing the P1488 code fix the issue on my 2016 Chevrolet Silverado?
Clearing the code will temporarily turn off the check engine light, but the underlying issue must be addressed to prevent the code from returning.
