P0705 TRANSMISSION RANGE SENSOR CIRCUIT MA

1998 Ford Escort

Transmission problem
1998 Ford Escort 4 cyl Front Wheel Drive Automatic

I have two problems that need to be fixed on my car. First off my serpentine belt keeps flying off, it doesn't matter what the weather is like (ie: raining, etc.) It'll fly off within the first 5 kms of driving. From what I'm thinking its probably caused by a pulley thats out of alignment or something like that. Secondly my OBD2 Code Reader is giving me a code " P0705 - Transmission Range Sensor Circuit malfunction (PRNDL Input)" What does that mean exactly? What I'd really like to find out is could either of these problems be DIY repairs or do they need to go to the shop? &Amp; if they do need to go to the shop I really can't afford to get ripped off by the mechanic so could you estimate about how much $ repairing these problems will be?

5 km you said, is this a USA Escort car . This answer is only for USA Escort. Maybe the same as yours.

Maybe you need a new assembly tensioner pulley. The spring inside the old pulley of yours is already soft. The assembly tensioner pulley keeps the serpentine belt tight at all times. Also, There is another idler pulley under the alternator, replace that too.

P0705 TR sensor is either misalligned or defective or circuit wire short. TR sensor is located on the transmission. Follow your shift cable going to the transmission. On the end of that cable, underneath it is the TR sesnor.
