SOURCE: 2001 bmw 740il output speed sensor location

hello ryk786, i/m not a hundred percent certain, but I think the output speed sensor is located at the back of the transmission. With the pan removed, if you look at the valve body and see the EDS valves and connectors, look about 2 inches back toward the end of the case and you should see a connector by itself. There should be a retaining torx bolt and spring holding the sensor in place. After installing the new sensor, do not over-tightend the bolt. The torque should be around 5-6 Nm.

2005 dodge stratus PO720, PO700, and U110c came up, BCM part of the last code ( fuel level) ?


Did you actually erase the codes after the first time?
Sounds like the speed sensor lost contact first, then the transmission went into limp home mode? So everything's fine now, contact was restored with the speed sensor. BCM is the body control module, kind of a nutty professor's idea to centralize a lot of body electrical wiring into a single control module, seems to cause more problems than it alleviates. Wouldn't be surprised if the speed sensor and the fuel level, like the rest of the dash cxluster is not all routed through the BCM. Well, it works now. When the problem re-occurs, you'll maybe be able to snuff it out. Bood luck.

Indictor light on dash is on my car doesnt take off in first gear 1998 740il bmw


Sounds like your car is in limp mode, which means its stuck in 2nd gear, basically you can get to where your going and that's bout it..problem is that there is bout 50 different reasons as to why this could happen, most common reason is a faulty speed sensor, does your speedometer work?, I believe there are 2 speed sensors on that car, if your speedo is working it may be the input speed sensor, the output speed sensor also runs the speedometer.. To be safe you need to have the codes scanned in the trans, if you have speed sensor codes you got lucky cause that's cheap compared to what it could be...

The trouble began by my van not shifting out of 2nd care... van had gone into limp mode. Shortly there after, the engine light came on and my van started to overheat. We ran the codes and got PO720,...


Hi,
The codes you gave are:
P0720 = Output shaft speed sensor error P0731 = First gear incorrect ratio Replacing the Output shaft speed sensor should clear that up and help your transmission. Around $20 or so. The limp mode is probably caused by a faulty cam position sensor or crankshaft position sensor. Overheating: Did you verify that your cooling fan is coming on? Kicking into a higher speed with the A/C on? Thermostat of the correct heat range and installed with spring end into engine block? Coolant is not rusty looking or weak? (check specific gravity) Flush and refill system if not nice and green or orange/ is rusty looking. Water pump is circulating coolant properly? (open radiator and observe circulation, feel top hose for fluid surging) if not, bad pump. Any of those will cause overheating. Hope that helps! Please rate this answer.....Thanks, Mike

My 91 dodge stealth is in limp mode how do i fix this transmission problem


Your car is in "limp"mode because the computer doesn't know what speed your doing,So it doesn't shift,
There are three possible reasons for this,
#1= input sensor faulty on transmission,
#2=output sensor faulty on transmission,
#3=speed sensor faulty on transmission,
you need to have the transmission codes read to know which one,Autozone checks codes for free.

well.. the output speed sensor is the output side of your transmission speed sensor... these are horrible on merc's... easily replaced... but a pain to get the correct one.. and this sensor could cause almost all the problems you list alone... but with such low miles it may be a warranty item? as it is on your transmission...
