Question about 2002 Volvo S80

3 Answers

Transmission Service Required message

2001 S80; 127000 miles well cared for. Codes indicate possible input sensor malfunction. Dealer wants to replace transmission. I asked that the sensor be replaced first before spending $3,500 on new transmission. Dealer says they don't do that; the sensor is internal and
by the time they tear down, repair and put back they would just as soon do a replacement. Some things to consider; transmission fluid is full,
doesn't smell burned and is maintianing its color. The car shifts fine and there has been no indication of any problem other than the light.
I am not getting the urgent red triangle but rather the orange caution triangle. Check engine light also comes on. We have cleared the codes and the car will run for 100-300 miles before the message comes back and the check engine light comes back on. Have taken the car to a transmission shop for a second opinion. What do you think?

They are correct as to the Location of the Sensor and, It would be a Time Consuming and Expensive Repair But, If you are not getting the Red Caution Light I would have the Tranny Flushed and Filled and see if it is not Just Buildup on the Sensor. It could actually Release itself. If not you will eventually have to get a Rebuild Buut, Try the Flush and Fill First.

In a Jeep, OBDII code P0700 indicates that the EATX (Transmission controller) has an active fault and has illuminated the MIL (Malfunction Indicator Lamp aka Check Engine light) via a BUS message. The specific fault must be acquired from the EATX via a DRBIII tool. So until you hook it up to a DRBIII scan tool, you really know what is wrong with your transmission. Input or Output Speed Sensor failures often cause this P0700 code and are a common failure part on Jeep Grand Cherokees. So take it to a dealer you trust or ask around for a transmission shop you could trust - they will have the DRBIII scan tool and you will pay them (in most cases) an hour's labor costs ($60-$100) to tell you what the internal codes are and what it MIGHT take to fix it. Or (this is what I would do), you can try replacing both Input and Output speed sensors yourself and see if that cures it. You will likely spend about $80-$100 on those 2 parts. The dealership will charge you about $180-$250 for those 2 parts plus another hour of labor to put them in. Good luck.

Volvo P0717 Input Speed Sensor


The P0700 is not a true fault code, it just means that the powertrain control module has requested the Transmission control module to turn on the check engine light to alert you of a fault. The P0717 is the one you need diagnosed, it is the real problem,.

2005 nissan almera,1.5letre.. fault code po725


P0725 NISSAN - Engine Speed Signal

The P0725 Codes is triggered when TCM does not receive the engine speed signal from ECM.

The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes:
- Open or shorted CKP sensor circuit condition
- Poor CKP sensor electrical connection
- Check communication error between the ECM and TCM
- Failed CKP Sensor

Possible solution:
Very common problem with Nissan vehicles, usually replacing the Crankshaft Position sensor takes care of the problem.

I use a site that deals with nothing but codes for automobiles, and this is what they gave me for your year, make and model of your car. PO128 is Electrical System failure. P1781 is Engine Torque Signal Circuit, and PO700 is Engine and Cooling. If you gave me the right codes, this is the answer Chevy gave me. hope this helps

PO456 is most times a gas cap or gasket,
to get an incorrect gear ratio the transmission has probably started to slip.

Change the fluid and filter first off in the transmission and use only atf+4 fluid and possibly the govenor pressure sensor,and change gas cap.

Check engine light with following codes p 1529 p0720 p0715


P1529 indicates that your TCM asked the ECM to turn on the check engine lamp.

The range switch and the output speed sensors are the items that are abnormally affecting the operation of the transmission. The diagnostic logic in your computer can distinguish these issues from one another, so you'll definitely want to do both. You have no diagnostic code for the input speed sensor (P0715) listed, so I have made no recommendation to replace it. In my opinion, it's not a labor-intensive repair, so I wouldn't recommend replacing it unless you have reason to believe it's bad.

DTC - P0720 (OUTPUT SHAFT SPEED SENSOR SYSTEM)
Code No. P0720 Output shaft speed sensor system
If the output from the output shaft speed sensor is continuously 50% lower than the vehicle speed for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h or more, it is judged to be an open circuit or short-circuit in the output shaft speed sensor and diagnostic trouble code No. P0720 is output. If diagnostic trouble code No. P0720 is output four times, the transmission is locked into 3rd gear or 2rid gear as a fail-safe measure.
Probable cause
Malfunction of the output shaft speed sensor
Malfunction of the transfer drive gear or driven gear
Malfunction of connector
Malfunction of the TCM

DTC - P0715 (INPUT SHAFT SPEED SENSOR SYSTEM)
Code No. P0715 input shaft speed sensor system
If no output pulse is detected from the input shaft speed sensor for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h (19 mph) or more, it is judged to be an open circuit or short-circuit in the input shaft speed sensor and diagnostic trouble code No. P0715 is output. If diagnostic trouble code P0715 is output four times, the transaxle is locked into 3rd gear or 2nd gear as a fail-safe measure.
Probable cause
Malfunction of the input shaft speed sensor
Malfunction of the underdrive clutch retainer
Malfunction of connector
Malfunction of the TCM

Is needed replace.

I WOULD TRY REPLACING THE INPUT SPEED SENSOR..A DEFECTIVE SPEED SENSOR CAN CAUSE ALL OF THESE FAULTS..IT IS LOCATED IN FRONT OF TRANS ABOVE SOLENOID PACK..IT IS THE ONE CLOSEST TO THE ENGINE..IT SCREWS INTO TO TRANSMISSION..A 1 INCH SOCKET FITS IT..ALSO CHECK WIRING TO BOTH SPEED SENSORS..A SENSOR IS ABOUT 35 BUCKS,AVAILABLE AT YOUR LOCAL DODGE DEALER..GET A NEW ONE AND YOU'LL SEE WHAT IT LOOKS LIKE..FAIRLY COMMON PROBLEM..HAVE REPLACED LOTS OF THEM
