Where is the knock sensor on a villager?
by Cayden Conor. The knock sensor on the 1993 through 1998 Mercury Villager 3.0-liter engine is located under the intake manifold. It checks for pre-ignition, otherwise known as spark knock. If it senses spark knock, it sends a signal to the programmable control module (PCM), which is the engine’s computer.
Can a knock sensor be good or bad?
We used voltmeter to test the knock sensor. It is not possible to say 100 percent if the knock sensor is good or bad. However, this test let you know if the sensor produces any signal at all. A bad sensor usually does not produce any signal at all. If in doubt we will recommend to replace the knock sensor. They are not very expensive.
How do you remove a knock sensor from a car?
Work the coolant crossover tube back and forth and pull it off the engine. Disconnect the knock sensor’s electrical connector. Unbolt and remove the knock sensor using the appropriate socket. Install the new sensor and tighten the bolt firmly.
What to do if your villager engine wont start?
Pull the fuel pump relay out of the box using the needle-nose pliers. Crank the engine over three or four times to relieve the fuel pressure. The Villager will not start. Disconnect the negative battery cable using the appropriate wrench. Place the drain pan under the radiator petcock.

What happens when a shop knock sensor fails?
A failed knock sensor will register a trouble code and illuminate the Check Engine lamp (CEL), although some engines will require multiple failure cycles before storing a code. Knock sensors don’t fail often, but if you suspect this problem, it’s one you need to move on quickly to head off engine damage. SHOP KNOCK SENSORS.
How do you install a new knock sensor?
Unbolt and remove the knock sensor using the appropriate socket. Install the new sensor and tighten the bolt firmly. Plug the new sensor’s electrical connector in. Reinstall the coolant crossover tube. Lay the new lower intake manifold gaskets on the cylinder heads, then position the lower intake manifold on the engine.
Is the knock sensor on a Chevy S10 4cyl compatible?
Apparently that is standard procedure in many shops when doing head gaskets on this engine. That being said, I researched to find a way around pulling the engine back apart. What I found was someone had done some research and claimed that the displacement of this 3VZE engine was similar to a Chevy S10 4cyl and that the knock sensor was compatible.
Where is the accelerator cable on a villager?
Loosen the locknut on the accelerator cable, then pull the cable out of its bracket on the top of the upper intake manifold. 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. Set it aside.
How does the knock sensor on an engine work?
If it senses spark knock, it sends a signal to the programmable control module (PCM), which is the engine’s computer. The knock sensor works by sensing the vibrations in the engine, caused by spark knock.
Where is the fuel pump relay on a villager?
Open the relay box, located near the driver’s-side fender well. Read the underside of the cover to determine which relay is the fuel pump relay. Pull the fuel pump relay out of the box using the needle-nose pliers. Crank the engine over three or four times to relieve the fuel pressure. The Villager will not start.
