Ok, today's the first time I have been home, and had a free day where it is not inhumane outside. Thanks to Sidewinder's post above, I went through& cleaned all the above grounds& also cleaned the body side termination of the bonding braid from the cylinder head to firewall. The shop I took it...

Thank you Sidewinder.

I had a few minutes to test on this& based on the suggestion of an old friend, I went back to basics, checking compression& fuel pressures. Fuel manifold pressure key on, engine off was 42, with the engine running I got right at 50psi. Compression I tested 1 revolution& after 3 or so to pump up...

Do you know what sensors are on the same circuit& which grounds they share? I am led to believe that often one power circuit would feed up to 6 of these sensors& often one ground will service the same number, where a bad ground on one will cause a back-feed& errors on others on that common power...

Part of my problem is schedule& free time. and not knowing what to look for on these later models or where to look for them. Plus the added fun of being somebody Else's vehicle, that I have now dropped 500 parts& labor into without much improvement in performance.

The Chrysler guy Said the Turbine speed sensor became an official item in 1999, but was pretty much a secret in 1998. the sensor is supposed to be on the side of the transmission around where the front pump would be. Edit to add: At this point, both the Chrysler Mechanic& my guy suspect an...

The computer compares the readings of the CKPOS & the turbine input sensor to determine torque converter slippage. I will have to check the distributor shaft for wobble. the NSS is located in the transmission position switch,a $400 item. there was an O-ring on the transmission that had been...

here are the codes we are getting now p1391 loss of crankshaft /camshaft position sensor input p0715 turbine input speed sensor also tcc. I have replaced both crankshaft& camshaft position sensors, and although the 1998 isn't supposed to have the turbine input sensor( dealer only item about...

The code he was picking up was turbine input sensor.

I'll double check in the morning& get back, but iirc it is related to crankshaft& camshaft position sensors.

I asked about swapping relays& the mechanic said he tried swapping one just like you say. I think we have tested& looked at all the obvious things, now we are looking for the odd things (the story of my life:jester: )

I friend recommended this site to me, As he said there was a considerable knowledge base here, so I may have a mystery for you to help solve. I have my Step-dads 1998 4.0 Cherokee sport in the shop, This started out as completely dead, would not start, with a code& symptoms indicating a...
