EGR Valve Wiring Diagram (w/ Manual Transmission)
NOTE: The above EGR valve wiring diagram applies only to 1996, 1997, 1998 1.6L (D16Y5 VTEC-E) Honda Civic HX with a manual transmission.
The exhaust gas recirculation (EGR) valve on your Honda Civic HX, with a manual transmission, is an assembly that consist of three different components. These 3 components are the: valve itself, the pintle solenoid and the pintle lift sensor.
The EGR pintle lift sensor is the component that gives the PCM feedback on the position of the EGR pintle as it's activated to open (or close) by the EGR pintle solenoid.
EGR Valve Wiring Diagram (w/ CVT Transmission)
NOTE: The above EGR valve wiring diagram applies only to 1996, 1997, 1998 1.6L (D16Y5 VTEC-E) Honda Civic HX with an automatic transmission.
The EGR control solenoid is a seperate component and not part of the EGR valve assembly as in the EGR valve used in the manual transmission equipped Honda Civic HX's.
EGR Valve Wiring Diagram (PART 2)
The GRN/BLK wire that connects (and feeds ground) to the EGR valve lift sensor also connects to several other sensors/components. The above wiring diagram should help to identify these components.
The YEL/BLU wire that connects (and supplies 5 Volts) to the EGR valve lift sensor also connects and feeds power to the TP sensor and fuel tank pressure sensor.
Where To Buy The EGR Valve And Save
You can buy the EGR valve for your Honda Civic in just about any auto parts store... but you'll spend a whole lot more because they mark it up quite a bit.
My suggestion is to buy it online... or at least comparison shop to get an idea of how much it costs and how much you can save.
