DTC Code P24B6 – What does this code mean?

<ul> <li><a href="/problems/engine-warning-light-on"><b>Engine Light ON</b></a>: The engine light or service engine soon warning light illuminates, indicating an issue with the particulate matter sensor heater control circuit. This could be linked to a high voltage condition in the circuit.</li> </ul>

<ul><li>The exhaust particulate matter sensor may be faulty, leading to incorrect voltage readings and triggering the error code.</li><li>An open or shorted harness in the exhaust particulate matter sensor can disrupt the electrical flow, causing high voltage issues.</li><li>Poor electrical connections in the exhaust particulate matter sensor circuit can result in unstable voltage levels, leading to the error code.</li></ul>

<ul> <li><b>Verify DTC Code</b>: Confirm the presence of DTC P24B6 using an OBD-II scanner. Clear the code and perform a test drive to see if it returns.</li> <li><b>Inspect Wiring and Connectors</b>: Check the wiring and connectors related to the particulate matter sensor heater for any signs of damage, corrosion, or disconnection.</li> <li><b>Measure Voltage Supply</b>: Use a multimeter to measure the voltage supply to the particulate matter sensor heater. Ensure it is within the manufacturer's specified range.</li> <li><b>Check Sensor Heater Resistance</b>: Measure the resistance of the particulate matter sensor heater. Compare the readings with the manufacturer's specifications to determine if the heater is functioning correctly.</li> <li><b>Inspect Control Module</b>: Examine the control module responsible for the sensor heater circuit. Look for any signs of malfunction or damage that could cause high voltage.</li> <li><b>Perform Continuity Test</b>: Conduct a continuity test on the circuit to ensure there are no open or short circuits present.</li> <li><b>Replace Faulty Components</b>: If any components are found to be faulty during the diagnostic process, replace them and clear the DTC code. Conduct a test drive to confirm the issue is resolved.</li></ul>

<p>The DTC P24B6 indicates a <b>critical</b> issue with the Particulate Matter Sensor Heater Control Circuit experiencing high voltage. This can lead to <ul><li>inaccurate readings of particulate matter levels</li><li>potential damage to the sensor</li><li>increased emissions</li></ul>. Ignoring this fault may result in <b>non-compliance with emission standards</b> and potential engine performance issues. Immediate attention is required to prevent further complications.</p>
