Definition of P24B4 Code The P24B4 OBD-II generic powertrain code indicates "Particulate Matter Sensor Heater Control Circuit Range/Performance". This code is triggered when the engine control module (ECM) detects a malfunction or performance issue with the particulate matter (PM) sensor heater circuit. In our experience, the P24B4 code occurs most frequently on European diesel vehicles,

Understanding and Diagnosing OBD-II Code P24A4 OBD-II diagnostic trouble code (DTC) P24A4 is defined as "Diesel Particulate Filter Soot Accumulation Excessive". This generic code has the same meaning for all vehicles equipped with OBD-II, though the specific repair steps may vary by make and model. In our experience, the P24A4 code occurs most frequently on

What does the P24A3 code mean? P24A3 is a generic powertrain code that stands for "Diesel Particulate Filter Restriction – Soot Accumulation Bank 2". It indicates that the engine control module (ECM) has detected excessive soot buildup in the diesel particulate filter (DPF) on bank 2 of the engine. Based on our experience at the

What is the P24A2 Code? The P24A2 is a generic OBD-II code that indicates "Particulate Filter Regeneration Incomplete (Bank 1)". It means there was an issue completing the regeneration cycle of the diesel particulate filter (DPF) on bank 1 of the engine's exhaust system. In our workshop, we've seen the P24A2 code pop up quite

Understanding and Resolving OBD-II Code P24A1 P24A1 is an OBD-II diagnostic trouble code (DTC) that indicates an issue with the diesel particulate filter (DPF) regeneration control system. Specifically, it means "Closed Loop Particulate Filter Regeneration Control At Limit – Temperature Too High". In our workshop, we've encountered the P24A1 code quite frequently, especially among European
Read More
Urgency and Driving Considerations When the P24A0 code is triggered, it indicates an issue with the diesel particulate filter (DPF) regeneration process. While it is not typically a critical issue that requires immediate stoppage, it is important to address it promptly to prevent further damage to the exhaust system. If possible, avoid extended idling and

What is Code P249E? OBD-II diagnostic trouble code (DTC) P249E stands for "Closed Loop Reductant Injection Control At Limit – Flow Too High". This code indicates that the vehicle's selective catalytic reduction (SCR) system, which injects diesel exhaust fluid (DEF) to reduce NOx emissions, is operating at its maximum limit due to excessively high DEF
Read More
Understanding P249D: Closed Loop Reductant Injection Control At Limit P249D is a diagnostic trouble code (DTC) that indicates an issue with the diesel exhaust fluid (DEF) system, specifically that the closed-loop reductant injection control is at its limit due to low flow. This code is common in diesel vehicles equipped with selective catalytic reduction (SCR)

Understanding the P2470 Fault Code: Causes, Diagnosis, and Repair The P2470 is a diagnostic trouble code (DTC) for "Exhaust Gas Temperature Sensor Circuit Low (Bank 1 Sensor 4)". This code indicates an issue with the exhaust gas temperature (EGT) sensor or its circuit. In our workshop, we've noticed that the P2470 code is particularly common
