Code 47 means Battery voltage sense input below target charging voltage during engine operation.
1st Thing i would check is the battery, to make sure it has a full charge and full amount of cold cranking amps and make sure all connection are clean and tight.
2ND If you have a voltmeter check and see if alternator is putting out enough volts should be close to 14.5 volts. If you have no way to check them most auto parts store will check them for free.
If i can help anymore please re post . Thanks dodge tec

Engine codes for 93 grand cherokee


Code 12 is Battery voltage to PCM disconnected within last 50 key-on cycles. So it's not a problem.
Code 47 is Battery under voltage. Probable cause is: Check the charging system.

I have a '93 jeep grand cherokee limited 5.2 v8.


Disconnecting your battery, as you must've done when changing the starter, will cause the ecu to revert to factory settings and the computer will have to relearn the proper idle for your jeep.

Will not start alot of turning over then you here fuel going through then it starts 93 jeep cherokee limited 5.0 v8


Your main ECU is in need of repair. Your jeep is displaying signs of the common delayed start problem. The check engine light does not light up, for a while, then when it finally does, the fuel pump gets power and it starts. Have your ecu repaired.

Why is my 93 jeep grand cherokee limited 5.2 v8 whining?


Did you check all the fluids? Power steering can whine when fluid levels get low. I would think of things that are driven by the engine: power steering pump (check the power steering fluid), AC compressor, water pump, and so on.

Check out the belt tensioner; make sure it's not too tight, and that the pulley is properly lubricated. If that doesn't fix it, ask your mechanic about timing belt issues (fairly soon).

Hope helps.
