Hello,

A few months ago, my check engine light came on. The ABS and TCS also
came on. I took it down to AutoZone and they ran a code on it. It came
back saying that there was an issue with the speed sensor. The car would
start hesitating around 5000 rpms and not accelerate properly. If I put
the car in neutral, I could red line the vehicle if I wanted to.

Long story short, I ended up replacing the input and output speed sensors.
The check engine went off, but the ABS and TCS lights stayed on. The
vehicle did not hesitate at 5K.

A couple of days later the check engine light came back on, and the
hesitation returned. I disconnected the battery and then reconnected, the
check enginge light went off and no hesitation.

Does anyone have any clue what is going on here? Help would be much
appreciated!

-Cameron

Presuming it's a V6, it's could be an issue with the vehicle speed sensor,
at the right front whee. But without actual trouble codes (and knowing
whether it's a four cylinder or V6), there's no actual way to do much more
than guess. At this point, I'd recommend having a look at the tone wheel
on the right axle. If you see nothing, wait until the lamps resurface,
have the codes checked, and report the actual code numbers.
