A '98 Jeep Wrangler of a client came with no speed reading with check engine light on. Scanned it and gave me codes P0500 and P0320. I taught a bad speed sensor for the first code, and the second code a consequence of the first fault. Am I correct? or, the P0320 code refers to other problem appart of the first.

Hope I'm right...

this jeep can't run good. sounds like it needs a new crank angle sensor, and possibly a new speed sensor. tell us a little more history about the jeep....wap

Jeep came running to the store I work. 2.5L engine with manual trans. The only job the owner did as I knew was sparkplugs change. But he couldn't change the #1 sparkplug so he came to do that and to scan the vehicle. The sparkplug was changed, scan was made, speed sensor was changed, codes erased, and the client leave the store with the Jeep the way he came (running). As I know he did not came back with any other complaints.
