P1488 2015 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 2015 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 2015 Chevrolet Silverado?
- Faulty Exhaust Particulate Matter Sensor
- Exhaust Particulate Matter Sensor harness is open or shorted
- Exhaust Particulate Matter Sensor circuit poor electrical connection

Frequently Asked Questions about P1488 2015 Chevrolet Silverado Code
1. What does the OBDII code P1488 mean on a 2015 Chevrolet Silverado?
P1488 indicates an issue with the Particulate Matter Sensor Protection Tube Performance, which is part of the diesel exhaust system responsible for monitoring soot levels.
2. What are the common symptoms of code P1488 on a 2015 Chevrolet Silverado?
Symptoms may include an illuminated check engine light, reduced engine performance, increased exhaust smoke, or poor fuel efficiency.
3. What causes the P1488 code to appear on a 2015 Chevrolet Silverado?
Common causes include a clogged or damaged particulate matter sensor protection tube, sensor contamination, or exhaust leaks near the sensor.
4. Can I drive my 2015 Chevrolet Silverado with the P1488 code?
While the truck may remain drivable, it's not recommended to ignore this code as it can lead to reduced fuel efficiency and potential damage to the exhaust system.
5. How do you diagnose the P1488 code on a 2015 Chevrolet Silverado?
A technician will use an OBDII scanner to confirm the code, inspect the particulate matter sensor and protection tube for damage or clogs, and check for exhaust leaks or wiring issues.
6. How is the P1488 code fixed on a 2015 Chevrolet Silverado?
Repairs may include cleaning or replacing the particulate matter sensor protection tube, replacing the sensor, fixing exhaust leaks, or addressing wiring problems.
7. How much does it cost to fix the P1488 code on a 2015 Chevrolet Silverado?
Repair costs can vary but typically range from $200 to $600, depending on whether the sensor or protection tube needs cleaning or replacement.
8. Can a dirty diesel particulate filter (DPF) cause the P1488 code?
Yes, a clogged DPF can increase soot levels and affect the particulate matter sensor's performance, potentially triggering the P1488 code.
9. Will resetting the check engine light clear the P1488 code permanently?
Resetting the light will clear the code temporarily, but if the underlying issue isn’t resolved, the code will return.
10. Is the P1488 code specific to diesel-powered 2015 Chevrolet Silverado models?
Yes, this code typically applies to diesel models as it relates to the particulate matter sensor in the diesel exhaust system.
