SOURCE: 2000 lincoln ls i got a trouble code p1633 (KAM)voltage to low

P1633 means KAM (Keep Alive Memory ) Voltage too low. the KAM is caused by low battery voltage and you replace the battery.When you replace the battery the KAM loses Memory and the problems resulting in what you are experiencing now.When replacing a new battery, reconnect the Positive cable first.And use a trickle battery charger set low to the cables before disconnectng the battery . this will keep the voltage to the ECM powered with enough voltage. All you can do now is make the computer relearn the way it should run. Disconnect the negative cable from the battery, wait a while 20 seconds or so. then reconnect the cable. I do not know if this is a temporary fix or not but it should re-program the computer.

A flashing light indicates that the engine is misfiring enough to damage the catalytic converter, this needs attention ASAP, otherwise after the misfiring is repaired, you will be buying a new catalytic converter, the damage may have already been done. as for the p1633 has the battery run low and you had to jump it off, or recharge the battery?

SOURCE: 2001 for tarous code p1633 what does that mean

P1633 means KAM (keep alive memory) power is low. The power that goes to the vehicles computer to hold its memory when the key is off has lost its power. I would start by checking fuses in the fuse panel in the engine compartment(near the radiator support). If the fuses are all good then I would test for power at the computer connector which is also in the engine compartment behind the engine. I don't have the pin number or wire color at the moment (I apologize) since the Ford website is down at the moment. I have repaired this problem in the past by installing another power wire to feed the circuit essentially bypassing the original circuit.
Hope this helps

SOURCE: i have code p1633 keep

I ahve gathered this information from the web...This can be an inexpensive or expensive problem!

Suspect the battery is chronically low; not accepting a charge and needs to be replaced.
The power cables from the battery may be corroded. These should be removed cleaned and retightened.
Check the wiring harness and connections to the Power Train Control Module. Use a contact cleaner/ lubricant and a brush to clean these connections then reseat them firmly. Also make sure there are no chipped or frayed wires as it travels through the engine compartment.

Check all the fuses and other components in the fuse box and the battery junction box to make sure they are in place firmly seated; fuses are good and clean from any corrosion on the clips. The location of these boxes is in your owners manual.

Alas it may be the PCM itself. That should be replaced by a mechanic.

Hope that helps

P1633 --Keep Alive Power Voltage Too Low

You provided no vehicle info

I would suspect battery connections or a near
dead battery

You could check the fuse but will have to use your
owners manual,we don't have any data for anything,
we are at home like you

Then the most likely cause is a poor wire connector

I suspect from your name,your not onto car electronics,
so a repair shop will be your only bet

They aren't too fond of fords or lincolns ,so your running
the show & telling them what to test & repair. Your looking
at diagnostic time, no parts or actual repairs

Mercury sable 2002 engine light stay on error code p1633 how do i fix this issue


This has to do with voltage falling too low for "Keep Alive Memory" (or KAM) to the PCM. First check the battery voltage, terminals etc. After that it could be anywhere in the wiring harness. See the link below for add'l help

It has a cheek enigen on and give the code P1633


When the Taurus PCM (Powertrain Control Module)(aka "the car's computer"), sees 9V DC (or less),
it sets the code P1633, so it means your battery's voltage was low recently. But since the computer
retains the code until it is reset, the battery voltage may be OK now. This is typical for cars
that have sat for awhile, and the tiny current drain of the clock slowly drains the battery until
the voltage drops below 9 Volts. Normal car Battery voltage is 12 Volts.
Fix: check the battery (with a DMM (digital multimeter)), and reset the code (with a code reader).
Workaround: have Advance/Autozone/PepBoys check the battery (free) and ignore the code.
