Possible causes Faulty Park/Neutral Position Switch Misadjusted Park/Neutral Position Switch Park/Neutral Position Switch harness is open or shorted Park/Neutral Position Switch circuit poor electrical connection What does this mean? When is the code detected? The transmission range switch detects the selector lever position and sends a signal to the TCM. Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) P0705 MERCEDES-BENZ Description The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM).
Hi, P0705 indicates your range sensor, which is on the top of the transmission where the cable attaches. When replacing the sensor, the new sensor must be properly adjusted. leave the screws slightly loose and set the transmission shifter in reverse. Turn the key on and watch the reverse lights while turning the sensor. When the lights come on, hold the sensor in place and tighten the screws. Please let me know if you have questions, and thanks for using FixYa.
Hi, you can see a full list of Jeep DTCs here: http://jsautosource.com/factory-manuals/dtc-definitions/full-list-of-all-definitions-for-dodge-chrystler-jeep-dtc-codes/
Your engine light will probably return immediately after clearing the codes until the P0700 is rectified. The 705 indicates your range sensor is out of adjustment or broken. The range sensor is mounted to the side of the transmission where the cable attaches. It may be adjustable. Normally, when the range sensor fails, the starter will not turn, because the sensor provides the park/neutral safety interlock to ensure the transmission is not in gear. Also, the range sensor usually includes the backup light switch. I usually adjust the sensor by putting the transmission in reverse, turning the key on, loosening the switch, and rotating it until the backup lights come on. Please let me know if you have questions and thanks for using FixYa.
This is an external problem.P1134 is telling us that upper O2 sensor on
bank 1 -which is firewall side- is responding slow and needs to be
replaced. P0705 is showing the transmission range switch -which is
located on the top of the transmission just under the battery tray- has
given up. That is why the shifter indicator lights acting weird.
Replacing these two parts will take care of your problem.
