Mercury is one of the leading manufacturers of low-cost cars that are frugal and environmentally-friendly. But first, do a diagnostic check before condemning it. It checks for pre-ignition, otherwise known as spark knock. After this, the skipping stopped for about 2 weeks then started again. Keeping a reliable Mercury Knock Sensor installed allows you to keep track of the timing of the spark plugs. This should set it's own fault code.
Then he determined that the knock sensor had its defect. If you have a code reader then use this to clear the codes. Using the picture in Reference 1, tighten the bolts and nuts in sequence to 30 inch-pounds of torque. As it requires considerable disassembly and an expensive new gasket set to reach it, I suggest you make very sure there is something wrong with it first. I pick the van up and it is running great! After he replaced both of them, the light remained on. I am scared at this point to drive the van so I pay to have it towed to a different mechanic. The harness plug in that plugs into the sensor has to be purchased even if ordered.
My 1999 Villager was running poorly; rough idle, lack of power at highway speeds and the engine problem light indicated random miss-fire, etc. Unbolt and remove the water outlet from the front cover. As it requires considerable disassembly and an expensive new gasket set to reach it, I suggest you make very sure there is something wrong with it first. On the second go-around, tighten the nuts to 18 foot-pounds of torque, then tighten the bolts to 10 foot-pounds of torque. Check engine light is on, when engine is cold, start up and put into drive, engine kills, start up and again engine kills. Remove the lower intake manifold. My mechanic said this would be the spark plugs buy maybe the wires so I paid to have them replaced a second time.
Place the upper intake gaskets on the lower intake manifold, then set the upper intake manifold on the gasket. Loosen the petcock and allow the antifreeze mixture to drain into the drain pan. If you need this part, I highly recommend buying it here as I had a good experience. It only retards timing 6 degrees if it senses spark knock. Putting 89 octane fuel in a car that requres 93 octane will cause engine knock. The computer analyzes these voltages and determines if they meet a pattern that is equal to engine knock. Work the coolant crossover tube back and forth and pull it off the engine.
Loosen the clamps on the crossover breather tube and remove the breather tube and the bracket from the upper engine front cover. You will have to remove the upper and lower intake mani … folds and coolant crossover pipe assembly to reach it. Check engine light is on, when engine is cold, start up and put into drive, engine kills, start up and again engine kills. This part is also sometimes called Mercury Villager Engine Sensors. Reinstall the components on the lower intake manifold in reverse order of removal. As it requires considerable disassembly and an expensive new gasket set to reach it, I suggest you make very sure there is something wrong with it first …. Took it in for emissions and it passed perfect! Place the drain pan under the radiator petcock.
If you're a seller, Fulfillment by Amazon can help you grow your business. Year Make Model Description 1999-2002 Mercury Villager Mercury Villager Engine Knock Sensor V6 3. Remove the cap and set it aside leave the spark plug wires attached to the cap. Unbolt the four fuel injection rail bolts. Just because you are receiving a trouble code for it does not mean there is anything wrong with it. The knock sensor is in the engine V under the intake manifolds and coolant crossover pipe. If the Villager has a speed control actuator, loosen the locknut, then remove the actuator from its bracket on the top of the upper intake manifold.
The pressure caused by vibrations from spark knock is converted to a voltage signal. A vehicle knock sensor is a sensor screwed into the engine''s block or cylinder head. Disconnect the rear heater valve vacuum hose from the upper intake manifold. Unbolt and remove the two left breather tube bracket bolts from the upper intake manifold. Take out the hold down and pull straight out, a little twisting motion will help with this. I am also interested in what other sensors may share this circuit as a previous answer indicated.
Remove the four manifold nuts. Remove the five Allen bolts from the upper intake manifold--these bolts hold the upper and lower intake manifold together. On the second go-around, tighten the nuts to 18 foot-pounds of torque, then tighten the bolts to 10 foot-pounds of torque. Pull the air cleaner-to-intake manifold hose off the engine. Pull the radiator hose off the intake manifold.
