This code is related to your transmission. You have gear ratio error codes in 1st, 2nd, and 3rd gear. You could check your transmission fluid and see if it's cherry red or burnt looking. My guess is you have a transmission that's gone out. Sorry for the bad news.but it's my line of work. If you had a input speed sensor code then I would say it's a problem with the sensor but since you didn't mention it's probably a transmission problem.

I have a 2001 vovlo s80 with the codes p1618 p0705 po733 how can i fix


PO705 is Transmission Range Sensor Circuit Malfunction. PO733 is Incorrect 3rd Gear Ration Information. P1618 means that the ECU and the TCM are not communicating properly. PO705 & PO733 can be related to P1618. Check the wiring going to the transmission. Look for a pinched wire from the car being put on a rack or possibly an accident you may have had recently. If you can find no problems with the wiring or connections then it is time to see a professional transmission expert. It may just be that the transmission has an internal problem.

THe blue smoke is oil, a considerable amount leaking into the combustion chamber and burning, either valve stem seal or piston rings. Check your oil and add regularly to prevent an engine seizure.
Also, you transmission need to be rebuilt.

Intermitten po720 2001 maxima is the input and output the same do you think its the sensor , wiring or tcm or ecm


This code can be caused by all of the things you mentioned, plus a damaged parking pawl ring on the transmission. This is what the sensor reads. For my money, I'd try replacing the sensor. They are relatively cheap compared to the alternatives and Nissan sensors have a reputation for early failure.

Hope this helps,
Dave

Code Reads PO733 & PO734, car runs great but these two codes show up when I check it out on my scanner. Any help or advice?


po733- gear 3 ratio incorrect, po734- gear 4 ratio incorrect. this is how to fix. You can try replacing the shift solenoids inside the transmission as long as the trans fluid is nice and clean looking. If the trans fluid is dark or burnt looking, it time for a new tranny
