2uzfe Ecu Pinout

The 2UZ uses a hot-wire MAF. Pin (Signal) and E2G (MAF Ground). If you use cheap wire splices, the voltage drop on the ground wire will shift the MAF reading by 10-15%. The engine will run lean at cruise and rich at WOT. Fix: Solder and heat shrink. Never use a T-tap on a MAF ground.

On 2003+ VVT-i models, check the ETCS fuse power and the M-REL circuit. If the electronic throttle motor isn't getting dedicated power, the engine will only idle. 2uzfe ecu pinout

Most swappers use the 2004-2006 Tundra or 2003-2005 Land Cruiser ECU. Here is the standard layout for the as you look at the harness side: The 2UZ uses a hot-wire MAF

: Post-2007 engines feature VVT-i, which manages throttle position and camshaft timing to improve efficiency across all RPM ranges. The engine will run lean at cruise and rich at WOT
