Code p0720 please help
Hello: I have a 2010 g37s convertible and have a check engine code p0720 (revolution speed sensor) and u0101 (not communication with the transmission control module) I see a couple videos how to change it for Do it myself but there is no videos for the infiniti and I don't find the sensor in my car,the problem is I call an infiniti dealer for service and they tell me that only if I change the sensor the problem don't fix,I have to buy additionally the transmission module,oil,etc to fix the problem and it cost me approx $2,500 dollars.
in all the videos I see for other models don't say nothing about replace all the parts,only the sensor, I don't know what to do,any help or advice please? Thanks https://cimg9.ibsrv.net/gimg/www.myg...1b57f4d4d8.png |
the auto trans in our cars are electronically controlled and all sensors, components, and module are mounted inside the trans. in order to get at that sensor they would need to drop the trans pan to access it. the trans module or shift plate or whatever they or you want to call it is bolted to the valve body along with the sensor which is mounted inside the housing somewhere. in addition i doubt changing that sensor will fix your problem due in part because when i see codes such as an internal speed sensor fault and not the vehicle speed sensor that set the malfunction light there is actually something mechanical that has taken a dump. meaning either something is worn out, broke, or come apart/loose.

i know the 90% of people with infiniti cars take cars to infiniti dealers or buy new one when the car causes much problems. also in the infiniti dealers work by hour and commisions and i don’t know,why all the cars damage only the sensor and the infiniti mechanics said this car damage the module and the module give signal to the sensor and not working. this no make sense,the sensor is a part that could be damage too. i call a transmition mechanic explaining the problem and he and i think the same,told me see a view videos: ( infiniti g35 p0720 sensor location ,1.05 minutes and infiniti g37 tear down,video is 20.15minutes ) maybe with only the sensor the problem will be fix,i am visit him next week to verify if the sensor its damage to replace it, i hope not to make a mistake so as not to spend so much money,wish me luck::biggthumpup: |
Works nice only changing the sensor
I take it to the transmission mechanic, replace only the sensor, also take transmission plug out,check and clean all the area, then put back in and it works, only cost me 300.00 and in Infiniti dealer charge me 2,200 to 2,500, thanks God what a relief
