Meta Description (SEO Focused):
Looking for a genuine replacement GC3A-5L239-AA particulate matter sensor (OEM 0281006657 / 0281006658) for your Ford F-250/F-350 6.7L Power Stroke diesel? Fix DTC errors, DEF system faults & check engine lights with our direct-fit PM exhaust sensor. Fast shipping for US heavy-duty truck owners.
H2: What Is the GC3A-5L239-AA Particulate Matter Sensor (OEM 0281006657 / 0281006658)?
H3: Core Function of a Diesel Particulate Matter (PM) Sensor
A particulate matter sensor is a critical exhaust emissions component mounted on the diesel particulate filter (DPF) assembly of Ford’s 6.7L Power Stroke diesel engines. The GC3A-5L239-AA factory OEM sensor (cross-referenced to Bosch part numbers 0281006657 and 0281006658) measures soot particle concentration exiting the DPF.
This sensor sends real-time data to the truck’s ECU to regulate:
- DPF regeneration cycles (active & passive regen)
- DEF (Diesel Exhaust Fluid) injection timing
- Exhaust backpressure monitoring
- Emissions compliance for EPA inspection & state emissions testing
Without a working GC3A-5L239-AA PM sensor, your Ford heavy-duty truck will trigger fault codes, limit engine power, and fail roadside emissions checks.

H3: Key Fitment Verification Tip for US Truck Owners
Always confirm compatibility via your truck’s VIN (Vehicle Identification Number) before purchase. Match the original part number stamped on your factory sensor: GC3A-5L239-AA, 0281006657, or 0281006658 to avoid misfitment for your exhaust DPF system.
H2: Common Symptoms of a Failed GC3A-5L239-AA Particulate Matter Sensor
US diesel truck drivers typically notice these warning signs when their OEM PM sensor (0281006657 / 0281006658) fails:
- Check Engine Light (CEL) Illumination Top diagnostic trouble codes (DTCs) linked to a faulty GC3A-5L239-AA sensor:
- P2452 (Particulate Matter Sensor Circuit)
- P2453 (PM Sensor Circuit Range/Performance)
- P2454 (PM Sensor Circuit Low Voltage)
- P2455 (PM Sensor Circuit High Voltage)
- P2463 (Excessive Soot Accumulation – Failed Regen Trigger)
- Reduced Engine Power / Limp Home Mode The ECU cuts power to protect the DPF if invalid PM readings are detected—common for work trucks hauling trailers, campers, or heavy payloads.
- DPF Regeneration Failure Stuck regen cycles lead to clogged DPF filters, expensive DPF cleaning, or full DPF replacement (costing $1,500–$3,000 at Ford dealerships).
- Failed State Emissions / OBD-II Inspection California, Texas, Illinois, and other states with strict diesel emissions testing will reject your truck with an active PM sensor fault code.
- Increased DEF Fluid Consumption The ECU over-doses DEF to compensate for incorrect soot readings, raising operational costs for fleet and personal truck owners.
H2: Why Choose Our Aftermarket GC3A-5L239-AA PM Sensor Over OEM Ford Dealership Parts?

H2: DIY Installation Steps for GC3A-5L239-AA (0281006657 / 0281006658) Particulate Matter Sensor
Step-by-step guide for US DIY mechanics (standard hand tools only: socket set, ratchet, anti-seize compound):
- Safely lift the truck on jack stands or a full-service lift, allow exhaust components to fully cool (minimum 2 hours after engine shutoff to avoid burns).
- Locate the particulate matter sensor threaded into the DPF exhaust pipe (upstream or downstream position per your OEM sensor location).
- Unplug the factory electrical connector from the PM sensor control module.
- Use a socket to unthread the old failed GC3A-5L239-AA sensor from the exhaust bung.
- Apply a thin layer of high-temperature anti-seize lubricant to the threads of the new replacement sensor.
- Thread the new PM sensor into the DPF bung and torque to factory Ford specification (25–30 ft-lbs).
- Reconnect the wiring harness plug to the sensor module.
- Clear stored DTC fault codes with an OBD-II diesel scanner, perform a short test drive to initiate DPF regen and verify the check engine light stays off.
H2: Frequently Asked Questions (FAQs – US Customer Focused)
H3: Can I drive my F-250 with a bad GC3A-5L239-AA particulate matter sensor?
Short-term highway driving is possible, but prolonged operation will clog your DPF filter and force costly repairs. Limp mode activation is highly likely during heavy towing or uphill driving.
H3: Is the 0281006657 interchangeable with 0281006658?
Yes, these two Bosch part numbers are direct cross-references for the GC3A-5L239-AA Ford OEM sensor and can replace one another for upstream/downstream DPF mounting positions.
H3: Does this sensor come with a warranty for US customers?
All our particulate matter sensors include a 2-year limited replacement warranty for continental United States buyers. We offer fast USPS/UPS ground shipping from domestic warehouses for quick delivery.
H3: Do I need to reflash the ECU after installing the new PM sensor?
No ECU programming or reflash is required. After clearing fault codes with an OBD scanner, the truck’s computer will auto-calibrate the new sensor within 10–15 miles of normal driving.
