Question about Toyota Cars & Trucks

Open Question

Im having problems with my 1996 toyota avalon xl. I did a diagnostic test on it and it showed it needed a transmission speed sensor so I replaced that over the weekend. I still wont move in drive.

The transmission speed sensor was replaced and the diagnostic test show no codes. Took battery cables off overnight and still acting the same. It looks like it wants to pull off but giving me a rough pull off in drive one minute and the next time around when in drive, it acts like its in neutral. Any other suggestions please...Thanks

SOURCE: 1995 Windstar OBD II showing codes PO340, PO171, and PO174.

Symptoms of a faulty Camshaft Position Sensor can include hard starting (or no starting), rough running/misfiring and/or loss of power.

Code 340 COULD be caused solely by a faulty Camshaft Position Sensor. However, this code refers to the entire circuit. So, replacing the sensor may not fix the issue. The problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM.

Codes 171 and 174 typically appear together. They are caused by the 02 sensors reading too much air (lean) in the exhaust. In most cases, simply cleaning the MAF sensor does the trick. I typically take it off and spray it with electronics or brake cleaner. Just make sure it dries before reinstalling. If this doesn't eliminate the codes, inspect all vacuum and PCV hoses, check for a dirty fuel filter and ensure the furl pressure is within limits.

For clarification, the first trip to the shop your car showed codes 402, 732, 733, 171 and 174. After changing the DPFE/EGR, did ALL those codes go away and now only codes 340, 171 and 174 exist? Or do you have the second set of codes in addition to the first codes?

Free registration, wealth of information.

For the record: if the sensors they're referring to are the input or output shaft speed sensors, they are very easy to find...just remove the air intake box (where the air filter is) and they're right there on top of the transmission. Input sensor is the one closer to the front of the vehicle, output towards the rear.

SOURCE: 2002 jeep liberty speed sensor

Jeep Liberty 2002 woahs !
by porth21 - 2/1/09 7:35 AM In reply to: Jeep Liberty 2002 speedometer not working by Dannywon
I have a 2002 Jeep Liberty Limited with the same problem. The main problem I have found to be the routing of the speed sensor wires located on the rear difrential. They are 2 blue wires on my jeep and probably the same on yours. The problem is that they rub on the E-brake cable and once the wire is exposed they short and the speedometer and any other options running off they speed sensor quit working and that includes the tranny shift points and can cause the torque converter to not unlock and cause stalls. I am having the same problem for the third time and chrysler and jeep are both aware of the problem and unwilling to repair the problem or post a recall.

Well, first do the service. Pull the pan down and look for metal shavings. If there is metal shavings your in for a transmission. If not, you may have a problem with one of the transmissions shift solenoids located near the valve body.
P.S. The Duramax has the Allison 1000 transmission not the dodge cummins and they are one of the best trannys on the market.

SOURCE: 1991 Caprice No reverse. Moves in neutral. All forward gears OK.

This is Ron out of Vero Beach Florida. I have been doing trannys for years. The problem you described is caused (more than likely) by a seized clutch pack. Depending on the trans, and your car should be RWD with a 700r4 tranny, there are several sets of clutch packs and at least one band. Automatic transmissions rely on fluid pressure to "engage" the correct set of clutch discs, at the right time , to engage and change gears. I have seen in the past, where a customer parks his car for the evening and the next morning, no move. What happened?? More than likely, a clutch pack was on it\'s way out but cause the car was hot the plates were free, but after cooling, they can weld themselves together and actually "lock-up". In the morning you know the end result. Your tip on "moves in Nuetral" is the give away. Ron

My 1996 Toyota Avalon was making a knocking sound while driving on the freeway then stalled the engine will not come back on it just makes a clicking sound and the code reads p1705


That code relates to the transmission:
It's the sensor that sits directly on top of the transmission case.. Easy fix.
This sensor detects the rotation speed of the direct clutch drum.
By comparing the direct clutch speed signal with the vehicle
speed sensor signal, the ECM detects the shift timing of the
gears and appropriately controls the engine torque and hydraulic
pressure in response to various conditions, thus performing
smooth gear shifting.
DTC No. DTC Detecting Condition Trouble Area
P1705
The ECM detects conditions (a), (b), (c), (d), (e) and (f) continuity
for 4 secs. or more.
(2?trip detection logic)
(a) Vehicle speed : 32 km/h (20 mph) or more
(b) 3rd or 4th gear
(c) NC2 < 300 rpm
(d) Park/neutral position switch: OFF
(e) Solenoid valves and vehicle speed sensor are normal
(f) L position: OFF
 Open or short in direct clutch speed sensor circuit

according to this site:
Error code P1705

It's not why your car won't start.

96 toyota avalon diagnostic code P1705


This is a fairly common problem more than likely what you're going to find is the revolution sensor on the top of the transmission just down from the bell housing has gone open. Remove the connector and ohm test the resistance through the sensor. You should have between 560 and 680 ohms of resistance. Check the pins in the connector and make sure there's no corrosion.

1996 toyota avalon xls vibrating on start and when in drive with brake applied


Hello

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems.

I have a code of p1705 on my avalon, I don't know what does really mean. it tells me that I have a problem wiht the clouch sensor. do I need to replace it and where is it located. thank you for your help.


Slippiung transmission
1. Check the resistance on the direct clutch speed sensor. 560 -680 ohms should be present.

2. Monitor the wave form pattern on the direct clutch speed sensor at the Engine Control Module (ECM) for a good wave form and no cutouts on the signal.

3. Check the fluid and the transmission condition. Check for slight slippage of the transmission.
