I purchased the 12685369 particulate sensor for a customer’s Chevy Silverado Duramax that kept throwing P2463 codes. Installation was plug-and-play, no extra programming needed. After clearing the fault code with an OBD scanner, the DPF regeneration works perfectly again. No recurring error lights for over 3 weeks. The build quality matches OEM parts, great cost-saving option for repair shops. Will restock for fleet maintenance jobs.
WJIECO Diesel sensor –
Fitment for my Duramax 6.6L is spot-on, wiring connector lines up perfectly. The sensor came pre-calibrated, so I didn’t need to visit a dealership for coding. I’ve been towing a heavy trailer for two weeks with zero DPF errors or power drops. Only minor suggestion: add a simple installation guide in the package. Overall a reliable aftermarket replacement to fix particulate sensor faults without the OEM dealer markup.
