Ok need help , when i put positive into b termal , neg onto battery i get huge fluctuations it jumps from .02 , once i wiggle harness its jumping 5.0-14,16.0 , i only get a reading when keys off , A to positive , B to negative . with key on It does Nothing whatsoever .. need that ground fix please cruiser

 

i get a reading key off , A to positive , B to negative .. its .50.. moves to .33 eventually

 

btw im using the 3 flat connector , i have a Automatic renix , also has another square connect 3 wires ,1 blank , only labeled A , B on 1side , other side PCD or something similiar

 

The Automatic style TPS has two connectors. One is for the ECU, the other goes to the TCU (trans computer).

 

cool lol , do you know which ground is connected to the TPS by chance? im guessing Dipstick? ive cleaned it maybe i need to run a ground directly to it?

 

Cruiser’s Renix Sensor Ground Test
　
This sensor ground circuit affects the CTS, TPS, IAT, MAP, ECU and diagnostic connector grounds. It’s very important and not something to overlook in diagnosing your Renix Jeep as it is common for the harnesses to have poor crimps causing poor grounds. If any or all of the sensors do not have a good ground, the signal the ECU receives from these sensors is inaccurate.
Set your meter to measure Ohms. Be sure the key is in the OFF position. Using the positive (red) lead of your ohmmeter, probe the B terminal of the flat 3 wire connector of the TPS . The letters are embossed on the connector itself.
Touch the black lead of your meter to the negative battery post. Wiggle the wiring harness where it runs parallel to the valve cover and also near the MAP sensor mounted on the firewall. If you have an 87 or 88 with the C101 connector mounted on the firewall above the brake booster, wiggle it, too.
You want to see as close to 0 ohms of resistance as possible. And when wiggling the harnesses/connectors the resistance value should stay low. If there is a variance in the values when wiggling the wires, you have a poor crimp/connection in the wiring harness or a poor ground at the engine dipstick tube stud. On 87 and 88 models, you could have a poor connection at the C101 connector as well.

ive cleaned and replace the ground strap to the dipstick , cleaned all connectors and dipstick mounting , any suggestions?

 

Not off hand, I'll pull a wiring diagram for ya in the AM.

got it all adjusted im good to go happy as can be thank you very much guys

 

What ended up fixing it?

 

i added another ground to the lower shock stud, along with rad support that ground on the dipstick is rediculous , everyhings fine now , tested the TPS and it was fine 17% of reference idles nicely now at 650rpm !

now to do brakes and windshield and im set for the winter

 

Excellent!!

What about the ECU algorithms and resetting, and all that other mumbo jumbo?

You got by withjout it? LOL.

 

Deffiently did not help me whatsoever lol thanks again for the help

 

probably seeing the ALFACL pulse width correction factor table...
