2008 Mercury Mariner 3.0L V6 Engine Control Module ECU PCM ECM Computer OEM 8L8A-APB

Description

Up for sale is a genuine OEM factory original engine control unit module (ECU / PCM / ECM) designed specifically for 2nd generation 2008 Mercury Mariner compact SUVs equipped with the 3.0L Duratec V6 engine and automatic transmission, matching Electronic Control Module, 3.0L (AT), ID 8L8A-APB specifications. Mounted securely inside the engine compartment on the rear firewall/apron assembly, this central powertrain control module governs electronic fuel injection timing, multi-coil ignition timing, electronic throttle control, automatic transmission shift solenoid scheduling, and emissions monitoring. It serves as the ideal direct replacement unit to resolve persistent check engine lights (MIL), coil-on-plug driver circuit failures causing engine misfires, crank-no-start conditions, erratic transmission shifting, internal circuit board degradation, or loss of CAN-bus network communication. Sourced directly from a solid donor vehicle, this factory Mercury PCM has been thoroughly cleaned, visually inspected, and bench-tested to confirm an intact aluminum casing housing, undamaged wiring harness connector headers, clean header pins, and solid circuit board power-up state. Installing an original equipment manufacturer engine computer guarantees factory electrical stability, precise sensor voltage reference outputs, and durable engine compartment thermal shielding. Note: Fits 2008 Mercury Mariner 3.0L V6 automatic models (Convenience, Premier trims, both FWD and 4WD) matching engineering part ID suffix 8L8A-APB (or engineering part number group 8L8A-12A650-APB).

CRITICAL PROGRAMMING & PATS IMMOBILIZER WARNING: Powertrain control modules are electronically linked to the vehicle's Passive Anti-Theft System (PATS) and instrument cluster. This module will NOT allow the engine to start straight out of the box. Professional programming, parameter reset, and VIN alignment using Ford diagnostic software (IDS / FDRS / FORScan) by a qualified technician or automotive locksmith is mandatory prior to operation. Please verify your original module's engineering part number stamped on the chassis label prior to purchase.
