Had transmission replaced in 2001 Mercury mini van. How does one reset the sensor so the van recognizes the new transmission?

Possible causes
- Faulty Transmission Range (TR) sensor
- Transmission Range (TR) sensor harness is open or shorted
- Transmission Range (TR) sensor circuit poor electrical connection

What are you trying to reset? Just the clock or all the selected stations? You can try disconnecting radio's fuse or the ground wire to the vans battery for a few minutes.

have the fuel pressure checked if it is ok then you most likely have a bad cam or crank sensor.. is the check engine light on? that will help to pinpoint the issue. if no check engine light then most likely its a fuel pump.

Sorry to say, but the mini vans have always been plagued with poor transmissions. Unless you know anything about transmissions you will need to take it to a transmission shop somewhere for diagnosis.

distributor cam sensor

I had a similar problem. Turned out it was a bad fuel rail pressure sensor. Thew a OBD-II Code P0193. Bought a new sensor and installed it in about an hour. Easy. $40. Depressurize the fuel system first by disconnecting the switch under the jack cover in the rear of the van.

Crank sensor is in the bell housing of the transmission. Cam sensor is in the distributor.

Turn the key on and off 3 cycles ending in on position (rapidly) watch odometer, codes should cycle through, if you see a p0700 it is going to be a transmission overhaul. :(

Check your inertia switch. This is usually located in the rear interior of the vehicle. It has a reset switch you hold for 3 seconds. It is a safety switch to kill the fuelpump in an accident. Can trip with door closings.

not an interference motor. change the timing belt to fix.

Just be sure it's not the fuel pump or distributor first.

Check for brown dust under distributor cap & rotor. If yes, replace distributor. Ebay for part.
