Trans Failsafe Program - Need Help
 

Old timer here with a new problem. I did use search and have already gone through a couple of usual tests.

Yesterday, the TFS message displayed alongside the SES on my wife's 2001 X5 with 90,000 miles. My first hunch was the battery as the battery was almost on the 6th year so replaced that. Checked the new battery with a multimeter with the car off and on and the voltages read 12.56 and 14.01 respectively so that was good and supposedly alternator is charging.

Truck cranks hard but eventually starts on the second try and idles rough and TSF comes on and gear possibly stuck in 3rd or 4th. There are no other lights, ABS, DSC etc.I have also cleaned the MAF. I do not have the OBDII as a friend borrowed it and I wont get it back till tomorrow. I had changed the transmission fluid last year including a new dropping the pan and putting in a new filter.

What else can I check on my own while I wait for the OBDII? Any help or suggestions will be greatly appreciated

I feel for ya man... I got the tfp blues as well... From what I gather from the forum there are to many things that would trip the warning... Gonna take mine to a main dealer Tuesday... Hoping for the best good luck with yours

Pulled two codes:

P0335 - Position Sensor A circuit malfunction
and
P0727 - Engine Circuit speed no signal.

I am guessing they are related. Any experts out there who think its the camshaft sensor gone bad? I am assuming its the intake camshaft sensor? This would definitely explain the hard crank and rough idle etc.

Is the intake camshaft sensor next to the oil filter cap?
