Hey guys,
I finally got around to checking out my CEL codes and i had a christmas basket full of them... A couple i know but others need info on... Thanks in advance

-P1492 Ambient/Batt Temp Sensor Volts Too High External temperature sensor input above acceptable voltage.
-P1492 (M) Ambient/Batt Temp Sensor Volts Too High Battery temperature sensor input voltage above an acceptable range.
-P0756 AW4 Shift Sol B (2-3) Functional Failure Shift solenoid B (2-3) functional fault - Asin transmission
-P0740 (M) Torq Con Clu, No RPM Drop at Lockup Relationship between engine and vehicle speeds indicated failure of torque convertor clutch lock-up system (TCC/PTU solenoid)
-P1694 Fault In Companion Module No CCD/J1850 messages received from the powertrain control module-Aisin transmission.
-P1694 (M) No CCD Messages Received From ECM Bus communication failure to PCM.
-P0500 (M) No Vehicle Speed Sensor Signal No vehicle speed sensor signal detected during road load conditions.
-P0500 (M) No Vehicle Speed Sensor Signal A vehicle speed signal was not detected.
-P0138 (M) 1/2 O2 Sensor Shorted To Voltage Oxygen sensor input voltage maintained above normal operating range.

What does the (M) stand for??
P0138 Right now i dont have a post cat o2 so thats an easy fix.
P1492 Its unplugged didnt think it would thow a code.. Owell already plugged back in..
P0500 I have to figure out why my speedogear continues to get chewed up.. Need help

p500 you got the gear clocked right and did you clear all codes and see if they all come back and wazzzzzzzz up

Yea i clocked and geared it correctly after i screwed up the first one i did.. I have a thread somewhere that i had questions about but didnt get much of an answer.. right now its no in../ https://www.cherokeeforum.com/f2/aw4...ed-help-61013/

But nothing much trying to get everything fixed up on the heep before i get the insurance and things to drive it.. No tag no registration no insurance and still need to pay taxes and things on it.. then i go and get the exhuast.. I like the altitude.

the way i learned code and there causes we always tackled the highest code num first a lot of times it would take care of others that show up

98jeepsrt6

Yea they all seem to be connected and the more i read the more confused im getting of what the code is and what it controls.. Ive seen some guesses but no answer on other vehicle with same code.. I hate doing research..

So in my case the highest one is the P1694 but i dont know what it is, im looking for it now.. but it can be many things..

freegdr

what i see is it is a communication prob in either the scanner or xj

98jeepsrt6

I think its the xj since thats where they wer qnd i cleared the coes and it cam back.. I want to know what sensor , relay, wire are conne ted with this.. I dont even know where to start looking for it.

98jeepsrt6

Bump...
sorry but need some help or suggestions of where to start. thanks

hmmm, codes not really my specialty since I have a Renix Jeep, but connected to what? are you asking where the OBD connects back to the XJ?

The best thing I can find talks about a lack of signals from the "CCD Bus to the ECM". Assuming the ECM on these is the same as the PCM, I'm going to make sure all my cables that plug into the master computer on the front driver's side engine wall are all in good shape and not cut, melted or pinched.

Yea cant seem to find it...

do you think its throwing that code because the truck is sitting not driving and shifting while scanning?

98jeepsrt6

Well when i first got the heep about a year ago, I had problem with her not shifting. At a cold start everything seem to run fine but when she was at operating temp it wouldnt shift into any gears.. It wwas like its stuck in nuetral.. I could rev all day and nothing would happen.. I seemed to have fixed that problem by changing out the trans filter and doing a flush. The filter was completely clogged to the point that the metal screen started popping out. Since i havent had any issues with her warming up and not shifting..

But i have had the problem where it feels sluggish.. i give it gas and it seems to push its weight nothing more.. I dont get the well known jeep launch.. Stuck in third gear.. and when it shifts it feels like OD.. No power just cruising.. So i think this would explain a couple codes.. about the trans..

What im going to do is check my soleniods today when i get out of work, and see what happens.. Ill prob just replace them.. Also while im ****ing around with the trans im going to pull of the tail housing and inspect the shaft becuase i think the gear that rotates my VSS speedogear is the reason why my 36 tooth gear keeps ending up like this:

Thats the gear on the shaft inside the tail housing ^^
