2002 Jeep Liberty Intermittant electrical problem - battery light

You could have a fuel delivery problem. Start by

• checking fuel pressure. Fuel injected cars are very fuel pressure sensitive. Fuel pressure is very important and must be within specifications. However, if the pressure is low, it does not mean the pump is bad.
• A plugged fuel filter, a pinched line, and low voltage at the pump can contribute to low fuel pressure. All three must be checked before replacing the pump.

if the battery light is coming on then you have two possibilities and tahs a faulty alternator or a faulty alternator warning light control either way you will need to change the alternator to fix the problem.Use a genuine bosch unit is my best advice and not a back street recon thing

The problem may be an intermittent problem with one of the wheel speed sensors, if one wheel speed data recieved by the ECU does not match the other 3 sensors the ECU will interpret that as a wheel slip or spin, this will cause the ECU to initiate the traction control.

Something shaking is almost always a cylinder misfiring.
Which is usually a bad plug or wire. But it could also be an intake manifold vacuum leak.

SOUND LIKE DEAD BATTERY.CHECK BATTERY CABLE FOR TIGHTNESS AND FREE FROM CORROSSION AT BATTERY POST AND BATTERY CABLES.MAKE SURE BATTERY VOLTAGE IS 12.5 VOLTS.IF NOT BATTERY NEED CHARGING AND TESTED.IF BATTERY GOOD.SOUND LIKE ALTERNATOR BAD.BEFORE REPLACING OR DISCONNECTING BATTERY CABLES OR BATTERY AND ALTERNATOR.TURN OFF RADIO SO YOU WONT LOSE PLAYING CODE.

may have a bad temp sensor for trany oil, or the cooler or lines may be restricked,the oil temp has to be checked when the light comes on, this will tell if its really hot or the sensor is bad, start there.

Try posting this under Appliances. This is the Auto Section

Yes get itscanned & reset
Cheers Rob

have you had the oil pressure checked somtimes that will happen if the pressure is to low and also if your using synthetic oil.

check the alt might not be charging the battery
