99 - 04 Jeep Grand Cherokee: how to replace transmission speed sensors [45RFE transmission]
Enjoyed the video or found it helpful? feel generous? you can donate on the main channel page. Thanks for watching! This is just a short video showing you how ...
link375 does this do anything with the car switching from the od going on
and off and the car overheating light coming on? Even though the car is not
over heating?
hi...i have a jeep liberty 06...wich has the speedometer that usually going
to stuck on 20km/h and sometimes going to be slow compared to my speed...so
i guess are these 2 sensor ? or can be the trasmission as well ? do you
think if I'm going to change these sensor it is gonna be ok after ???
thanks !
+Alessandro Terracciano That actually sounds like something is wrong with your TCM (transmission control module) - basically the computer that controls the transmission. Try the speed sensors first as it's a much cheaper repair. If that doesn't fix it then it's probably your TCM or it could also just be loose cables or a bad dashboard instrument panel.
Forget the WSS as these have nothing to do with your transmission problem.
On vehicles where the speed is taken at the WSS (2007-up) one of the WSS is
the one in charge of that AND often IT IS NOT published, typical... But
that's not you. P0730 means that the range switch or pressure switches say
4th gear, but comparison between ISS and OSS doesn't match that. ECM knows
the ratio of ISS-to-OSS on the waveform, so it knows the trans is slipping.
Range, ISS, OSS/WSS can cause erroneous codes.
OK, as usual I need year, make, model and engine size. Assuming your
vehicle is older, there's only one VSS. 2008 and up, on SOME systems the
WSS from the ABS is used to signal the ECM for vehicle speed. So if your
speedometer works then chances are VSS is fine. Concentrate on ISS, and if
fine then your tranny is slipping. You are not cluttering the posts, on the
contrary. Ask away and do it here so that someone with your issue can
benefit. That's why I do this. THanks and good luck.
OK thanks and my vehicle is a 2002 mazda protege with a 1.6 zm engine in it
it has abs speed sensors on all four wheels just wanted to know 1. does my
ecm takes output readings from the tront sensors or both front and back? 2.
well you said if my speedometer works properly then chances are my wss are
fine? what are the chances of it throwing a p0730 incorrect gear ratio
code? 3. after reading what mryemen74 posted should i clean them just to be
sure that this isnt the culprit thanks
You can fix this problem with STP Brake Parts Cleaner assists in the
prevention of uneven braking, noise and chattering by quickly dissolving
and washing away lining dust, brake fluid, oily road film and grit to leave
brake surfaces clean, without disassembly, and also can be used with clean
your wheel speed sensor by open the speed sensor scart of cable connection
which is near of wheel base for all, almost time problem came from cables
scart lose!
OK, the pressure switches array is mounted to the valve body. They're
exactly that, small pressure switches bolted as an array. Each pressure
switch has a small hydraulic hole. Every time the trans effects a shift,
there's a different pressure combination, so hole 1, 3 & 4 have no press. &
2 and 5 with pressure. THis is a feedback system to the ECM, which is
compares the range, ISS and OSS. Most trannies do have pressure switches.
Hope that helped.
ok thanks your talking about solends lol ok my bad i should of known well i
try cleaning the wss they are really gunked up i read that most people
fixed there p0730 code by cleaning out there valve bodies as well it seems
to be a hydraulic problem others say a p0730 code is sensor related and has
nothing to do with bands, seal, clutches etc well im offcially stumped i'll
after checking all the sensors you stated for resistance and continuity
cont-
Hey me again I didt want to clutter your posts anyways if my guages work
properly eg speedometer and tachometer can my wss still be faulty and give
me the p0730 incorrect gear ratio? i'm about to test them per fsm for
resistance also which sensors do my fwd protege use to tell the ecm the
speed the vehicle is going the front sensors only or front and back
sensors??
So in other words a p0730 code is most likely a faulty tranny range sensor
or pressure switch or possible internal failure? when you say pressure
switch are you talking about the pressure control soleniod inside the valve
body? what other pressure switch are there in my tranny? im really out of
ideas when it comes to electrical stuff to check
Hello, just FYI even if you disconnect the pressure reg. solenoid, the
trans pressure should go to max high. So a short or faulty pressure sol.
would still not drop the pressure. That's also a test you could do, if you
haven't already, is disconnect the PS and see what happens. Though I should
mention it. Good luck.
Ok today I Tested the WSS got good ohm reading according to my fsm but when
i tried using my multimeter to get a ac reading as per fsm i go nothing can
you shed any light on the subject? the meter is a fluke auto range unit and
yes i confirmed that its working properly thanks!
why are you now telling me this lol keep those ideas coming lol so what
your saying go back into my valve body and disconnect the pressure reg sol
and when i do a pressure test again i should see my pressure increase to
max?
Ok, from this description, anytime pressure drops like that, depending on
where you're doing the PT it points to the pump or related components. As
you said, pump seals come to mind or pump itself. Hope that helped.
ok after reading it a couple times i understand what you mean im reading my
manual and it says low pressure in the forward gears only, means a forward
clutch hydraulic failure eg clutches what do you think??
Ok did the pressure test today on idle the pressure is within spec but on
the stall test all tests came back below specs what can this indicate? bad
seals ? valvebody problem? anyways thanks for your help!!
What's fsm? Don't use the MM to check AC. On MM the AC setting is an
averaging measurement, which is not accurate. Use Graphing multimeter or
scope. You want at least 2 volts peak-to-peak.
