This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the sensor that checks the temperature of the stuff coming out of the car's exhaust. It's like a thermometer for the car's pollution filter, and it's not working all the time.
The P24CA code is triggered when the engine control module (ECM) detects an intermittent issue in the temperature circuit of the particulate matter sensor.
The particulate matter sensor is used to monitor the amount of soot in the exhaust gases. This sensor includes a temperature circuit that helps ensure accurate readings. If the temperature circuit has intermittent connectivity or faults, it can cause inaccurate sensor readings, leading to the P24CA code.
• Check Engine Light illuminated
• Possible decrease in engine performance
• Increased emissions
• Faulty particulate matter sensor
• Damaged wiring or connectors in the sensor circuit
• ECM software issue
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors of the particulate matter sensor for damage.
• Test the sensor for proper operation.
• Replace the particulate matter sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Update ECM software if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado
• Dodge Ram 2500
• Regularly inspect and maintain exhaust system components.
• Ensure software updates are applied to the ECM.
• Avoid driving in conditions that could damage exhaust components.
Sensor Issue
• Have the vehicle inspected by a professional if the Check Engine Light is on.
• Avoid ignoring the issue as it can lead to further damage.
• Consider regular maintenance checks to prevent such issues.
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code has become more common with the increased use of particulate matter sensors in modern diesel engines.
Moderate – It should be addressed soon to avoid potential damage to the exhaust system.
Driving with a malfunctioning emissions system can lead to increased pollution and may not meet legal emissions standards.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The particulate matter sensor is typically located in the exhaust system, near the diesel particulate filter.
Q: Can I drive with a P24CA code?
A: It's not recommended to drive for extended periods with this code, as it can lead to increased emissions and potential damage to the exhaust system.
Q: How can I prevent this code from appearing?
A: Regular maintenance and inspections of the exhaust system can help prevent issues with the particulate matter sensor.
