This solenoid meters vacuum from the engine driven vacuum pump to the variable nozzle turbo actuator, and it is a well documented failure point on the VDJ79, VDJ76 and VDJ78: water and dust ingress kills the unit and corrodes the connector, and the result is low boost, gutless response, limp mode and a boost control fault code. It gets blamed on the turbo constantly, but this solenoid is one of the most common real culprits, at a fraction of the cost of a turbo.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background: #C8102E; color: #fff;\"\u003e\n\u003cth colspan=\"2\" style=\"padding: 10px; text-align: left;\"\u003eSpecifications\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom: 1px solid #333;\"\u003e\n\u003ctd style=\"padding: 10px; color: #aaa;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e25850-51010 (genuine OEM, brand new, made in Japan)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom: 1px solid #333;\"\u003e\n\u003ctd style=\"padding: 10px; color: #aaa;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003eBoost control solenoid \/ electric vacuum regulating valve (E-VRV \/ VSV)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom: 1px solid #333;\"\u003e\n\u003ctd style=\"padding: 10px; color: #aaa;\"\u003eFitment\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003eLandcruiser 70 Series (VDJ70 family): VDJ76, VDJ78, VDJ79, 4.5L 1VD-FTV V8 single turbo, 2007 onwards\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom: 1px solid #333;\"\u003e\n\u003ctd style=\"padding: 10px; color: #aaa;\"\u003eFunction\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003eRegulates vacuum supply to the variable nozzle turbo actuator for boost control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; color: #aaa;\"\u003eIn the Box\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e1 x genuine OEM boost control solenoid valve assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cdetails style=\"border: 1px solid #333; border-radius: 6px; margin: 10px 0; padding: 0;\"\u003e \u003csummary style=\"padding: 12px; cursor: pointer; font-weight: 600; color: #fff;\"\u003eFitment Notes\u003c\/summary\u003e\n\u003cdiv style=\"padding: 0 12px 12px;\"\u003e\n\u003cp\u003eFits all single turbo 1VD-FTV 70 Series variants: VDJ76 wagon, VDJ78 Troop Carrier and VDJ79 single and dual cab, 2007 to current.

Before condemning the solenoid, unplug the connector and inspect it for corrosion or moisture, since water ingress is the most common root cause and a corroded connector will kill a new solenoid just as fast. Check the vacuum lines to and from the valve for perishing, splits or oil contamination, then check the solenoid coil resistance against factory spec with a multimeter. An open circuit reading confirms a dead solenoid. One important distinction: a P1251 overboost code often means the turbo nozzle vanes are sticking rather than the solenoid failing, so verify free movement of the VNT actuator lever before buying parts.
