This summary uses the existing diagnostic information shown in full below.
Your car has a special sensor that checks for tiny bits of dirt in the exhaust. This code means that the sensor is having trouble reading the dirt levels correctly.
The P24DA code indicates that the particulate matter sensor, which monitors the amount of soot or dirt particles in the exhaust, is not functioning properly for Bank 1 of the engine.
The particulate matter sensor is designed to measure the concentration of soot in the exhaust gases. When the sensor detects an anomaly in its readings or fails to get a proper sample from the exhaust stream, the engine control module (ECM) triggers the P24DA code. This could be due to a sensor malfunction, wiring issue, or exhaust leak.
• Check Engine Light is on
• Decreased fuel efficiency
• Possible increase in exhaust smoke
• Faulty particulate matter sensor
• Wiring or connector issues
• Exhaust leak before the sensor
Particulate Matter: Tiny particles of soot or dirt found in exhaust gases.
Bank 1: Refers to the side of the engine with cylinder 1, typically in V-type engines.
• Use an OBD-II scanner to verify the code.
• Inspect the particulate matter sensor and its wiring.
• Check for any exhaust leaks before the sensor.
• Replace the particulate matter sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Fix any exhaust leaks found before the sensor.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Ram 1500
• Regular maintenance of the exhaust system
• Timely replacement of sensors
• Routine checks for exhaust leaks
Sensor Issue
• Avoid driving long distances until the issue is fixed.
• Consult with a professional mechanic for accurate diagnosis.
Check with your vehicle manufacturer; emissions-related components may be covered under warranty.
This code has become more common with the increased use of particulate matter sensors in diesel and some gasoline engines to meet emissions standards.
Moderate – It should be addressed soon to avoid potential damage to the engine or exhaust system.
Driving with a faulty particulate matter sensor can lead to increased emissions, which may not comply with local environmental regulations.
• Engine running at normal operating temperature
• Vehicle at idle or during normal driving conditions
The particulate matter sensor is typically located in the exhaust system, near the catalytic converter or diesel particulate filter.
Q: Can I drive with a P24DA code?
A: While the car may still be drivable, it's best to fix the issue soon to prevent further damage and ensure compliance with emissions standards.
Q: What happens if I ignore this code?
A: Ignoring the code can lead to increased emissions, potential damage to the exhaust system, and reduced fuel efficiency.

Fitment Required · Vehicle-fitment part
Relevant when catalyst-efficiency or emissions faults persist after proper diagnosis.
Catalyst-efficiency faults sometimes point toward converter problems after proper testing.
Catalytic converters are highly vehicle-specific and should not be purchased by code alone.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
