DESCRIPTION
Product Overview
- When removing, blocking off, or deleting a faulty EGR valve on classic 1986s and 1995s Ford trucks, the factory engine control computer detects the missing electrical resistance from the EGR Valve Position sensor. This causes the dashboard to illuminate a constant CEL and triggers stored fault codes (such as Ford OBD-1 Codes 31, 33, or 34).
- The EGR Performance Simulator / Eliminator Plug is an electronic bypass module engineered to solve this exact issue. Designed as a direct plug-and-play harness bridge, it connects directly into your truck's factory 3-pin EVP wiring harness.
- The module sends a fixed, closed-position voltage signal back to the engine computer, convincing it that the EGR valve is installed and fully operational—clearing CEL fault codes without splicing or cutting wires.
-
This is NOT an EGR defeat device, this device does not disable the EGR functions. It is connected to the wiring harness to keep the check engine light off, yet remain functional for other check engine light problems in off-road /race track applications, where EGR is not applicable. The purchaser (end user) bears full responsibility for any decisions made upon the end use of this item and all consequential liabilities thereof.
Key Features
- Plug-and-Play Installation: Plugs directly into your factory 3-pin wiring harness pigtail—no wire stripping, cutting, or soldering required.
- Eliminates Check Engine Lights: Sends a constant "closed valve" voltage signal back to the computer to clear persistent EGR fault codes.
- Prevents Fail-Safe Computer Modes: Stops the EEC-IV ECU from pulling timing or running rich due to missing EGR feedback signals.
- Weatherproof & Vibration Resistant: Features a durable molded connector housing with a locking latch to withstand engine bay heat, moisture, and road vibration.
Installation Instructions:
- Disconnect wiring harness from EGR valve sensor and assure that connector is clean and not corroded.
Dielectric grease inside the connector is normal and should not be removed.
- Firmly insert the EGR Eliminator into the wiring harness until locking tab locks to assure a good connection. Using electrical tape or a zip tie, secure the EGR Eliminator and wiring harness to a solid object, such as a nearby wiring harness to prevent the EGR Eliminator from bouncing and creating a bad connection in the future.
- Start the vehicle and check to assure the Check Engine Light is not illuminated. If the EGR Eliminator has a bad connection or has not been properly installed, the CEL light should immediately illuminate upon start-up and remain on.
- Note: After the EGR Eliminator is installed, when checking computer codes it is normal to receive a code 33 / 332. Although this code exists, it will not trigger the CEL unless other codes are also present.
FAQ
Q: Does this electronic plug physically block off exhaust gases?
A: No, this is an electronic simulator plug only. To physically block exhaust gases from entering your intake manifold, you must also install a solid metal EGR block-off plate.The standard plate has narrower bolt center spacing, while the universal/V8 plate has wider bolt spacing.
Q: Will this simulator work on a 1996 or newer Ford truck?
A: No. 1996 and newer Ford trucks feature OBD-II systems with DPFE (Delta Pressure Feedback) sensors. This plugin is strictly engineered for 1986–1995 Ford EEC-IV (OBD-1) systems with 3-pin EVP connectors.
Q: How do I install this simulator plug?
A: Simply locate the 3-pin connector attached to the top of your factory EGR Valve Position (EVP) sensor, unplug it from the valve, and snap this simulator plug directly into the factory wiring harness until the tab clicks.
Q: Will I need to clear stored computer codes after plugging it in?
A: Yes. Disconnect your negative battery cable for 10–15 minutes after installation to clear old, stored EGR codes from the EEC-IV memory.
Q: Why is my Check Engine Light (CEL) still on after plugging in the simulator?
A: The EEC-IV computer stores historical codes in its memory. You must disconnect the negative battery terminal for 10–15 minutes to clear old memory. If the light returns, use an OBD-1 scanner to check for non-EGR fault codes (such as O2 or TPS sensors).
