All Known Issues

2.9 CRDi High-Pressure Fuel Pump Internal Disintegration and Swarf Contamination

SeriousFuel System

The Delphi common-rail high-pressure injection pump fitted to the 2.9-litre CRDi diesel engine is prone to internal mechanical degradation. As the internal cam and rollers break down, they shed microscopic metallic swarf into the fuel lines, contaminating the common fuel rail, clogging the fuel filter, and jamming the diesel injectors. Early warning signs include engine power surging, severe hesitation under acceleration, and prolonged cranking before starting. Left unresolved, the metal debris circulates through the entire fuel system, requiring a full fuel tank flush or replacement alongside new pump and injectors.

Est. Repair Cost: £600–£3,200
Warning Signs:

Sudden surges in engine power followed immediately by cutting out or limp mode, Sluggish throttle response and severe hesitation when accelerating on dual carriageways, Extended cranking and failure to start due to fuel rail pressure loss

What to Inspect:
  • Remove the diesel fuel filter and inspect the drained fuel in a clean container with a magnet or torch for fine metallic swarf
  • Test-drive under sustained acceleration up an incline to verify the engine delivers continuous power without cutting out
  • Review service documentation for previous fuel system repairs or evidence of replacement fuel metering valves and pumps

Automatic Transmission Output Speed Sensor Failure and Third-Gear Limp Mode

ModerateGearbox & Transmission

On automatic Sedona models, the electronic transmission output speed sensor mounted atop the gearbox casing suffers from heat fatigue and internal circuit failure. When signal output to the transmission control module drops out, the gearbox abruptly triggers failsafe mode, locking into third gear while cruising on the motorway and refusing to shift into top gear or overdrive. Drivers also report erratic gear hunting, delayed engagement, and severe jolts when shifting into Drive at a standstill. Renewing the speed sensor and wiring plug is essential to restore proper shift operation.

Est. Repair Cost: £140–£390
Warning Signs:

Gearbox abruptly locking into third gear limp mode while driving at motorway speeds, Transmission hunting between gears or flaring revs before shifting up, Severe mechanical thump or jolt when engaging Drive or Reverse from stationary

What to Inspect:
  • Test drive through all forward gears at 50 to 70 mph to ensure smooth, timely upshifts into top gear
  • Check transmission fluid colour and smell on the dipstick to ensure it is not burnt or black
  • Scan the OBD-II diagnostic system for transmission speed sensor error codes such as P0720 or P0722

Buying Tips for 2002 Kia Sedona

  • Inspect the operation of both sliding side doors (electric on high-spec models) for smooth gliding on tracks and secure latching
  • Check the condition of the 2.9 CRDi engine oil and cooling system, looking for signs of oil contamination or cooling hose degradation
  • Inspect the rear subframe, chassis outriggers, and brake pipe runs for road salt corrosion that can lead to MOT structural failure
  • Confirm that the front and rear heating and ventilation blowers both output hot and cold air, as rear underbody coolant pipes are prone to leaking
  • Test the manual clutch pedal effort and check for shudder, as the Sedona heavy kerb weight puts considerable strain on the driveline
