Oil Pump Failure, VGT Turbo Carbon Buildup, Injector Wear, Cooling-Fan-Control-Circuit Fault Leading to Thermal Derate, and Crank/Cam-Sync No-Start (No Injector Pulse)

Engine / Cooling System · severity: Moderate to High - oil pump failure risks serious engine damage if ignored (low oil pressure); turbo/injector wear are more gradual, performance-affecting issues; a cooling-fan-circuit fault left unaddressed can allow the engine to overheat, at which point the PCM automatically enters a protective derate (reduced power) mode - a real, Ford-documented safety behaviour, not a separate defect. The crank/cam-sync no-start finding (added 2026-08-19) is genuinely more severe than the other faults on this card in one specific sense - it is a real, complete no-start, not a power-reduction on a running engine - though it is also a real, intentional PCM protective behaviour (withholding injection without a plausible sync) rather than evidence of catastrophic internal damage. · confidence: 50/100 · 8 cited sources

Symptoms to watch for

  • Ticking noise from the engine, low oil pressure, or an oil pressure warning light (oil pump)
  • Reduced performance or power, sometimes linked to carbon-fouled turbo vanes sticking (worse with DPF/short-trip driving)
  • Rough idle, misfires, or reduced performance from injector wear at higher mileage
  • Any of the above alongside an EGR-related warning light or split intercooler hose (a visible boost leak)
  • VERIFIED FINDING (added 2026-08-06): a coolant temperature warning light and/or the engine control light illuminating together with a genuine, noticeable drop in power - if this coincides with a stored cooling-fan-circuit fault code, the low power is very likely the vehicle's own protective thermal-derate response, not a separate, unrelated fault (the specific fault code and what it means are covered in the full report). The cooling fan itself may be silently stuck off (or stuck on) well before the derate response is ever triggered - a coolant temperature gauge running higher than normal, especially at idle or in slow traffic, is a real, earlier warning sign worth checking before power loss ever occurs
  • VERIFIED FINDING (added 2026-08-06, second code investigated): random, sometimes intermittent loss of power, possible stalling, delayed acceleration, or sudden transmission-shift irregularities occurring alongside a stored CAN-bus data-integrity fault code - real sources describe this as the PCM entering a protective mode specifically because it can no longer trust data it's receiving over the CAN bus (the specific fault code and what it means are covered in the full report). Unlike the cooling-fan-derate pathway above, this does NOT require the engine to have run hot first - it's a direct, live response to bad/implausible network data, meaning power loss can appear suddenly rather than building up gradually
  • VERIFIED FINDING (added 2026-08-19, third code pattern investigated): a genuine crank-but-no-start condition (engine turns over on the starter but does not fire) with P0335 and/or P0341 stored, where fuel rail pressure at the HPFP matches the commanded/desired value but no injectors are being pulsed - real, multi-source research confirms this is a mechanically coherent, real pattern on this engine, not a contradictory or confusing set of symptoms. The HPFP is cam-driven and can mechanically achieve correct rail pressure independent of the PCM's injection-timing logic; injector PULSE commands, however, require the PCM to have a plausible combined crank+cam sync to know each cylinder's actual position in its cycle - without that plausible sync, the PCM will withhold injector pulses entirely as a protective measure, even with a fuel system that is otherwise ready. This is a different, more serious symptom picture than the P0480/U0401 power-loss findings above (which affect a running engine); this is a genuine no-start.
The specific fault codes and inspection steps to check before you buy, a full repair-cost estimate, TSB/recall reference, and the buyer negotiation tip for this issue are included in the R99 vehicle report.
