BOSCH?
but the harness colors are unique. on the car.
so when is this.???? 1.6L SOHC, or the DOHC?

The wiring diagram shows the wiring color code, Power rating and connector plug used. The wiring diagram explains the vehicle's electrical connections with color code. It's a bit complicated to understand.

Problem with ford explorer v8 reading high voltage a sensor 1 bank 1


Clear the computer. Then if the reading is still high, you may have to replace the wire or the sensor. I don't have the specs for the O2 sensor available, could be sensor was bad and you happened to catch the connector problem but did not find the cause of your woes.

Now some O2 wiring has resistor properties, so shortening will change feedback value. Just fixing a pin connector should be okay. Also, the O2 sensor can sometimes have a micro cooling tube moulded into the wires. This type of O2 has its own heating element and vents excess heat through microtube. Try new O2.

My trooper is giving like 6 miles to the gallon its a V6 2.8 engine. I dont know where th oxygen scensor connect.


Hello! I have the wiring to your engine and perhaps a solution...The wire color from the ECM on Connector D pin #7 is White/Green and goes to the O2 sensor...The color at the O2 sensor is Black...White/Blue is connector D pin #1...wire colors that have aged are easily mistaken White looks Yellow with age...connect the O2 sensor to D-7...The O2 sensor is White/Green NOT White/Blue (which looks like Yellow/Blue) this wire is the Check Engine Connector...Tell me how many wires are either cut or misplaced? If we eliminate wiring we can concentrate on why your getting 6 miles /Gal...

If the vehicle backfires or runs poorly My next suggestions are to check the plug wires to be sure they are in the correct place...and #2 to check the timing...the left bank=1, 3, 5 and the right bank=2, 4, 6...Firing order is1, 2, 3, 4, 5, 6...CCW on the distributor...Stick with me and we'll have it purring. see timing below...
