Ford Transmission :: Check Engine Light On / OD Light Flashing Sometimes - Code P1747
I have a 1998 expedition 4.6 4x4 check engine light on od light flashing sometimes checked it and got p1747 code i was told epc solenoid or short on trans wiring. I already dropped the trans pan, looking for a step by step easy way to diagnose and find the short or if i need to replace any of the solenoids. I have voltmeter and taste light....

1998 F150, XL, 4.6, auto 138k miles. Idles perfect, give it gas 1 time, fine. Second time it sputters. Third time it sounds awful but will Idle perfect. Put in drive, bucks, sputters, jumps, and damn near dies. Threw code P1747 EPC solenoid. Next day truck runs perfect check engine light goes out. Two weeks go by starts to sputter again and check engine light comes back on. Bad ECM?
View 1 RepliesFord Super Duty (1999-2016) :: P1747 Code - EPC Solenoid Short Circuit
I have a f350 2000 4x4 automatic 170.000 miles. Service light on and OD light flashing. I have code p1747 "EPC solenoid short circuit"
This code make that the engine runs slow without power and hard shifting. I change all the solenoid body and check all wiring.
Later using a voltmeter i separate EPC solenoid wiring and see that have 5 volt. If I don't accelerate more 2000rpm OD light is not flashing and truck works normal but slow.
When I accelerate more than 2000rpm OD light begin to flash and transmission fail more. I check that EPC wires mark about 0 volts when OD light is flashing. Transmission hydraulic system seems to be ok because oil is very red and clean. Maybe another sensor is making this failure....
Ford Super Duty (1999-2016) :: Code P1747 - Shudders And Dies When Drop It In Gear?
It's a 1999 f250sd 5.4l auto. Has code p1747. Truck shudders and almost dies when you drop it in gear, put it back in park idles fine. I have read all the post on here about this and checked wires from trans up to pcm look and test well. Tested plug c1048 wires with the digital meter to body ground with battery unhooked and got 6.66k ohms on pin 11 circuit 925, 421 ohms pins 1 and 12. Plugged c1048 back to trans checked 925 w/y wire at plug c103 got 9.1 ohms back to trans. Is the EPC solenoid bad or is it pcm? I think its epc but want to verify before i take trans apart.

F250 7.3L diesel started to flash OD light, goes into limp mode, code p1747. No other codes. Have had issues for a couple of years where the truck would not shift into gear for awhile; sometimes a couple of minutes till it would engage. Have done lots of diagnostics. Visual check harness. Have 12v on pins 1&12 on harness at transmission plug. Plug had some ATF visible, but cleaned it up and continuity good. (with 4" exhaust hard to get to connector).
Checked all solenoid wires with a DVM back to plug at PCM for continuity and shorts, all good. Pulled transmission pack and checked resistance on all solenoids except temp varistor all within specs. Removed Banks Trans Command and rewired tranny plug and pulled Ottomind chip from PCM. Still goes into limp mode and throws code. Did not see any bad solder joints or burns inside PCM by the way.
Seems like PCM right? But here is a complication to my issues. For over a year I have been having electrical issues like the radio not working and windows not working intermittently after starting up. After running for awhile or on restart would work fine. Sounds like the Instrument Cluster issues or relays.(?)
Will be pulling IC and checking for any bad solder joints. However, did not throw p1747 till just recently and now my radio has really gone wonky. It comes on when key is on automatically and then proceeds to cycle through settings; AM-FM-CD.
So questions are, "Is it possible that a bad Instrument Cluster can cause a p1747 code?" "Bad Ground to Tranny" "Can a bad PCM cause a electrical issue in IC??" "Are these 2 separate issues?"

Prius (2001-03) :: Error Code P3030 And P3009 - Bad Transmission?
Could a bad transmission cause error code P3030 and P3009?
This car has no other symptoms other than the Mil light and the check engine light.
Prius (2001-03) :: Shuddering Transmission - Code P3125 And P3120?
Working on a 2002 prius with 153k miles. bought it with a "Bad transmission" diagnosed by toyota dealer. Got I home and did a quick check but there were no codes. I drove it about 50 feet into my garage where it would shudder badly while being driven which from my experience sounds like a bad MG2 motor. Drained the oil and thought hhmmm th oil does not smell bad and neither did it look burned. Proceeded to pull the mg2 but found it looked brand new, no burned spots or any such thing. SO I put it back together and think its a bad invertor. put on a different invertor that I have lying in my garage that I "think" is good and start the car. get code p3125 and p3120 and still have the bad shuddering when i try to drive it..Is there any way to test it further before I pull the trans and put a new trans back in?

I've got 95k miles on my 2001.5 and have been noticing that the transmission seems to shift pretty hard. Today it seemed like it was hardest in the 3rd to 2nd downshift. I got it checked out a couple of months ago and the dealer said it was the throttle body (which I haven't cleaned yet).

Before the question, this is what I have, 2001 V6 4-motion, Automatic. So tonight I was driving home from work. As I started off, the car shifted 1st-2nd fine, then when it hit third it just revs, felt like it was slipping or missing then kick to forth or second hard, then lit up all the the PRND234 on the dash instead of being in just drive. When I pulled over and restarted my car it clear but did the same thing. What is going on??? It happened once before (for a split second) but has been fine ever since. I just bought the car 3 months ago and the car has ran solid since i purchased it.

I have a 2001 1.8T Passat. I bought it used recently and have had tons of problems. I have been getting a lean air code for some time now and I think I recently resolved that. I had to replace a few vacuum lines, MAF, exhaust flex pipe (it was broken), fuel filter and fuel pressure regulator. The car was still running bad and throwing a lean air code (Bank 1) so I finally changed the O2 sensor and I think that did the trick. Now every time I start the car I get misfires until is warms up. I get misfires on all cylinders along with the multiple misfire code.
View 5 RepliesPassat (B5) :: 2001 - MIL Light On With DTC Code P0171 Lean System
I have a 2001 Passat 1.8T that has the pesky MIL light on with a DTC code P0171 lean system. I have sent it to the mechanic many times to no avail. What the mechanic did was replacement of the MAF, O2 sensors, checked intake manifold leak as well as exhaust manifold leak. His last attempt was to check for clogged injectors and fuel filter and they were in good condition. He says the ECM is bad. I was able to retrieve freeze frame data as well as live data which shows that the computer is compensating what it thought was lean by having very positive LTFT of 22.6. I don't believe the ECM is bad but cannot be sure. There is one more thing that was not checked by the mechanic is the EGR valve. Could that be the cause of my woes - the lean system?

2001.5 1.8t, I have this p0343 code when I used the scan tool at murrays or oreileys whatever the h they are now (it means something like cam angle sensor high input). The t-belt was due for service a while ago , am I looking at a sensor problem or a wiring problem or a timing/engine problem? How should I check and where? I hear the timing belt can be a pain on the 1.8s, I have done a mk4 trans and a bit of other stuff but I do have a lot going on right at the moment and I'm not sure if I have time. I have a feeling if I take it in for service they will probably find blow through from the turbo and pull the engine because of "sludge".

So my trans clicks and jerks every time it downshifts into 2nd but that is the only time it does it. When i down shift using the tip shift it doesn't do anything and it all feels normal. What it could be being that it is just when it downshifts into second.

Passat (B5) :: 2001 - P0430 Code / Stutter And Misfire After Cold Start
2001 V6 Passat with 125k miles throwing a P0430 code.
Having trouble on cold starts, takes about 10 minutes to finally get it to turn over. When it does the idle is extremely rough. For the first 1/4 mile the car bucks, stutters, and misfires. After that it runs fine and starts fine when already warm. I am noticing slightly decreased gas mileage but nothing major.
Valve cover gaskets were replaced 2 months ago, but were leaking oil for at least a year before I could afford to have them replaced. I am still noticing some oil leakage, however not as much as before. I have had both O2 sensors replaced twice in the past 5 years. Timing belt was replaced at 98k. What might be causing the starting issues?
Passat (B5) :: 2001 - Code P0171 Too Lean Bank 1 - Emission Light Comes On
I recently had some work done on my 2001 VW Passat 1.8T (timing, water pump, major tune up). IT had 72K miles.....
Now I'm getting the following:
Code P0171 Too Lean (Bank 1).
Emission Light turns on / off.
Check engine light comes on and stays on after about 20 miles. Can this be the oxygen sensor?
Ford Transmission :: 622 Code - Shift Solenoid?

View 4 RepliesTacoma :: Code P0770 - Transmission Fault Identification
I own an '02 Toyota Tacoma v6 3.4L 4-speed automatic. After a 2-hour highway drive (not too common, small town) the other day, I started to experience transmission issues (wouldn't always switch gears properly), and the check engine light came on. My scanner indicated P0770 (Shift Solenoid E Malfunction), a transmission fault.
I've spoken with my mechanic, and I've done some research online. My understanding is that it could be a shift solenoid, the valve body, the torque converter clutch, or even just low transmission fluid.
I have owned this truck since '05/28k miles. It now has 95k miles. At about 35k, the dealership installed a new transmission (maybe the former owner was a city-driver, or something), and I had basic dealer transmission service about 30k miles ago. I have an appointment to take it to a local shop (a Ford authorized service center, that also services other makes/models) in a few days.
Except for infrequent highway driving, I don't drive the vehicle "hard" at all. I have the vehicle fully serviced by the dealer at recommended intervals. I have been advised that if this fix requires more than basic transmission service, that I should take it to the dealership (factory tools, etc).
These are some observations about the malfunction:
1) The engine/transmission is still cold (just started the engine). I shift from P to R, to back out of my driveway. The transmission seems to be "stuck" in neutral/park. 5-10 seconds pass, finally transmission engages R gear. Switching from R to D, vehicle operates normally.
2) While driving normally, I accelerate steadily from 20-40mph. The transmission hesitates before switching from 2nd-3rd gear (peaking at 3k rpm, holding steady). When I take my foot off the accelerator slightly, then re-apply it, the vehicle shifts. (EDIT: Subsequent to this same post on another forum, I have been told that first gen Tacomas often have a cold tranny 2nd to 3rd shift hesitation, and I have seen it before, but it's arguably more noticeable since this recent problem developed.)
The transmission has only 60k relatively "easy" miles on it.
Prius (2004-09) :: Code P0A63 And Transmission Slipping
I have a 2006 Prius with 103k miles that runs and drives great but sometimes with no warning will display the red triangle and check engine light and seem to slip out of gear. All I can do is coast to a safe spot to reset the codes. Once I reset the code it runs fine again.
