Product Overview

**as seen on** This is used to test the EGR Temp Sensor on the 1FZFE OBDI Engine. This plug will insure the engine's computer receives the correct value to prevent a trouble code from being thrown.  This can temporarily disable the EGR system, allowing full testing.

**PLEASE NOTE** Some late 1994 1FZFE engines were OBDII.  In that case, you should use the 1995-1997 EGR Temp Sensor Test Plug Kit

    Plug fixed the EGR CEL issue for my all-new-parts but still-faulting SYSTEM. Rapid service from Huddexpo

    Worth the money. Use a 14mm crows foot to slip it on the old sensor to remove it. Prevents the nasty build up and recirculation which kill 1fz’s

    I finalllllllly got that pesky CEL to go away while I........ test the rest of my system to ensure I have no CEL lights. Im a bit of a Neanderthal knuckle dragger and had a few questions and the HudExpo team was quick and fast to answer any of my questions and give excellent customer support! 10/10 Will use this company for any future needs they offer.
