Speed sensor replacement

My van was running strange and the battery light comes off and on. I looked under the hood and a sensor (around the ac compressor) and I can't find where it hooks up?

    I meant the sensor was unhooked and could see where it went.

SOURCE: Blower motor now only works in 5th speed, 1 to 4 not working

You are going to have to make a connector for your resistor to fit into the adapater under the dash. the new resistor doesnt reach the terminals on the connector. Even though it clips in place it doesnt reach. I took a piece of small soldier and put in the connector then plugged it in and it worked just fine. When you unplug the relay it will not work in any speed.

SOURCE: Similar Problem: Van bogs down when you step on the gas

2 simple causes for your symptoms would be water in the fuel tank (pour drygas into the tank to alleviate this problem) or a leak in the exhaust system. If both items don't apply, check for any vacuum leaks under the hood. You've isolated the problem to either vacuum leaks or a fuel problem. Hopefully, this will give you a general area to look and solve your problem. Best of luck.

Sounds like there is a blown piston, to be sure have a compression test done on that #2 cylinder, if the reading is low, then you'll know.
A friend of mine had a 95 that did simular things only a little more,
it started smoking, dash lights flickered, etc. Finally, he had to get rid of it, the piston rod went through the engine block.

My 2002 dodge intrepid 2.7 has a power surge issue. I hit the gas and the lights go bright but then the gauges on the dash stop working. Hit the gas again and they start working for a second but go off...

When you accelerate the engine it rocks a bit under the hood. A loose/internally broken ground wire/cable under the hood is a possibility. Look for any and all wires/cables under the hood that might be loose. Wiggle all of these wires and don't forget any ground wires coming off the negative battery post. There are, I believe, ground wires at different areas under the hood. You might find your problem with one of these ground wires. The other possibility is at idle not a ton of charge is being generated from the charging system. Above idle an over charging voltage regulator can be the problem. It may be integrated into the PCM or be part of the alternator. A voltage charge test will reveal this. So, there are two possible sources of malfunction. Best of luck. And don't give up, you'll figure it out.

Maintenance light coming on, then the oil light.

The maintenance light is telling you that the cpu has found faults in sensors and is shutting down the engine to prevent engine failure. Have the codes read and replace that which is faulty with genuine units.

Coolant temp runs hot after about 20 minutes of driving. and when idled. Replaced thermostat looking to replace water pump too?

Your electric fan should come on around 220 degrees or so, if it does not you need to replace the sensor on the left front side of the block. The fan should come on immediately if you have AC and turn it on. If it does not check the relay in the fuse box under the hood, and related fuses. Unplug the electric fan and turn the ac on and check for power. It could be your fan motor quit. Usually if the fan does not come on when the AC is turned on, and it does not come on when car reaches 220 degrees, the motor is most likely the culprit.

Where is the transmission intake speed sensor

the input speed sensor is pretty easy to find.

With the hood open and standing in front of the van you should see the transmission on the drivers side of the vehicle. look under the two transmission cooler lines that are connected to the transmission. You will see a two wire connector plugged into a light brown/cream colored sensor. That is the input speed sensor. Usually the lines need to be removed in order to replace it. A one inch socket or wrench will also be needed to loosen/tighten the sensor.

Eventually you will be asking about the output speed sensor. It looks exactly the same as the input. It is located to the right (drivers side) of the input speed sensor as you standing in front of the vehicle. It is usually easier to see/access/replace from under the vehicle.

I have 98 olds intrigue and the temp gage reads normal not hot but the light comes on so i look under the hood nothing hot except the top of the ac unit and its not even on

Hello, Under the hood and look around the intake manifold/plenum. There should be square nut senor, and 5/8" wrench would probably remove the sensor. This sensor has just one wire plug into it. The sensor is thermal switch which activated at an certain temperature, example: 250 degree F.
It just a switch. Find this send and remove the wire, see if this doesn't turn off the idiot temp light off. GB..stewbison

Check and or replace your speed sensor if that does not work replace the instrument cluster - you can find one at almost any salvage yard.

Ac controls quit working blower fan is running on high all thetime. compressor is not working.

fan elays are under hood in black box by battery. 3 of them. 2 for high speed, 1 for low speed. Default is high speed when there is a probem.

Suspect maybe they shorted something out when fixing dent. Did they do any welding on the van? Connecting the cables to the body can sometimes send voltage where it's not wanted.
