Do I need calibration or coding after install?
Generally no coding required. Follow the OEM depressurise and prime procedure, then verify commanded versus actual rail pressure with a scan tool and clear any DTCs.

What symptoms indicate a failing SCV?
Hard starting, rough idle, throttle hesitation, surging, limp mode, poor fuel economy, or rail pressure deviation codes (P0087/P0088) are common signs.

Will other part numbers cross over?
Common supersessions include 294200-0690, 294200-0691, 294200-0692 and some 294200-0669x series for HP4 pumps. If in doubt, contact us with your VIN.

Do I need an adapter kit?
Only if your existing SCV is the short version. Most 1VD-FTV LandCruisers have long SCV fitment. If unsure, send us a photo of your current SCV or your VIN.

Can I install this myself?
Yes, it is a straightforward replacement if you are comfortable with basic diesel fuel system work. Follow proper fuel system depressurisation procedure and torque specifications.

How long does an SCV typically last?
Lifespan varies with fuel quality, operating conditions and maintenance. Symptoms typically appear after 200,000 to 300,000 plus km.
