#1848 of 2519 Re: 1997 Villager Problem with A/T not shifting [farnorth2]

Follow up to my transmission shifting problems.
Installing a new TPS (Throttle Position Sensor) solved the problem.
What seemed like a slipping transmission was just the TPS not sending the signals that tell the transmission when to shift gears.
Everything seems to be working great and we erased the codes by taking of the battery ground for a few minutes.
Have gone out for three drives with it and no Check Engine light has returned....so far...not even the EGR code.
I am so glad I found info on the web that told us that many Mercury Villager and Nissan Quest owners have needlessly replaced transmissions when it was only the TPS. So if you ever have transmission problems...don't replace the transmission before you make sure your Throttle Position Sensor is the culprit first.

I have a 1996 Vilager.
Amazing, I had the exact same problems and codes. Actually, I had a 3rd. and fourth gear a/t code instead of 1st gear.
What I found was:
1. broken hose ( about 2 inches long) at the EGR-BPT valve.
2. TPS tested faulty, but acually was working properly; it only had to be rotated slightly. The TPS sends a signal indicating the engine being at idle. Apparently this signal is very important to the trans. control module, because that is what was causing my transmission problems!!!!!!!!! I don't remember the specifics, but I used the Haynes repair manual - it tells you to adjust the TPS so that at idle you have a certain voltage (I think 5v). Do yourself a favor and probe the wiring harness to check to voltage with the connector connected.
I still have the knock sensor code. testing says that the sensor is bad, but I don't believe it (maybe because of the price and the dificulty of changing it - need to remove the upper and lower intake manifold!)
Hope this helps. I'm curious to know how you make out with your knock sensor.

I guess I should have checked the new messages before sending the previous message. Anyway, my check engine light also cleared after adjusting the TPS; however, it came back about a month later: KNOCK SENSOR again.
#1851 of 2519 97 Villager DTC P0135 problem w/oxygen sensor heater circuit.
May 26, 2005 (2:25 pm)
I have a 97 villager. The Check Engine lights was on recently. It comes out OBDII DTC P0135 (O2 Sensor Heater Circuit Bank 1 Sensor 1) and the following OBD Monitor Readiness Status:
Catalyst: Not Ready
Oxygen Sensor: Not Ready
Oxygen Sensor Heater: Not Ready
EGR System: Not Ready
I was focus on the P0135 issue first, replaced the upstream Oxygen Sensor and then erased the DTC. After the 20 minutes driving, I parked it on my driveway and turned off ignition. Waited for about 5 minutes and turned on the ignition again. The Check Engine light was returned. Problem was not fixed. It's not the Oxygen Sensor Heater problem. It's the circuit problem, but I don't know where the problem is. I will be very much appreciate if anybody can share their experience on this board.
#1852 of 2519 95 Quest thumping noise when in gear
May 27, 2005 (10:37 am)
I have a 95 Quest, 98k miles. Just in the last month, I noticed a thumping sound when in gear, no noise when parked and engine reving. No loss of power, I replaced all spark plugs, doesn't look like misfires. Again, engine sounds fine when reving in park. But as soon as I put it in gear and not even going fast, the thumping sound is heard, it also increases with gas.
Any ideas where I should look? I'm guessing tranny problems - trans oil is fine.
Maybe fuel filter?
#1853 of 2519 washer output clogged
May 28, 2005 (9:30 pm)
The front windsheild washer squiters are clogged. I've eliminated other causes and now I realize the clog is in the line UNDER THE PLASTIC COVER UNDER THE WIPER ARMS. How do I get the cover off to see the final section of hocing and the bottom of the squirters?
#1854 of 2519 93 Quest engine control module (computer) problem
May 29, 2005 (4:37 pm)
We just bought this GXE w/170k miles less than a week ago - the owner said he'd just spent $425+/- fixing the timing belt - he had just recently repo'd it - the buyers had abandoned it - we checked it out - the oil, etc - drove it - everything appeared fine - no check engine lights, no smoking - then Fri night 5/27 - it just stopped at a stop sign & it sounded like it would start - my husband thought it sounded like the engine was flooding but we ended up pushing it into a parking lot & towing it - at first we thought it was the fuel pump - but it's working - then we changed the distributor cap - the mechanic working on it showed us how the fuel injectors are receiving power even when the key is off - he said this means there is a short in the system & all the lines (according to schematics) lead to the computer - the mechanic saw that a line had been disconnected - he reconnected it - but the car didn't start - the distributor cap is getting spark - the ignition is working - any advice? Oh - at first he couldn't find the computer - he has since found it - he brought one from the salvage yard where he works - but it's not the same - anyone familiar with this problem? any advice would be most appreciated! Thanx
#1855 of 2519 Re: Thanks for the input folks.. and now another question for you all... [etudes]
May 30, 2005 (4:43 pm)
Don't have any input on you're EGR problem but have a question about a 2002 post of cold start ticking? Did you ever figure it out and/or fix it? I'm having the same problem...occasional loud ticking on a cold start. Temps are in the 70's and I'm using 5W30 so I'm wondering if I have serious issues. Mail me at jeffreyjbraggcomcast.net
#1856 of 2519 2002 Villager Fan Problem
May 31, 2005 (10:16 am)
I have a 2002 Mercury Villager Sport. The blower comes on every ten seconds or so when it is idling. I have taken it to the local dealership and they hooked it up to some machine and say they find nothing. Is this normal for a car to do. I've never seen one do this before.
#1857 of 2519 '99-'02 Quest/Villager
May 31, 2005 (12:01 pm)
I am a satisfied owner of a '93 Villager with 170K and I have been planning to trade it in for a newer one, mostly for the double doors. Since I have a bunch of kids and need the 2nd row bench seat, I'm limiting my search to non-captain's chair '99-'00 Quest SE's or '01-'02 GXE's (and the Villager equivalents). Can anyone tell me if there are any advantages of the '01-'02 over the '99-'00 models or vice-versa?
