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

fix what the codes says is wrong, cancel the light with a scanner

Then you did not fix the problem. Codes are not cut and dry, it can be the part the wiring to it or in rare cases a defective Powertrain control module (PCM)

i will look it up and get back ti you tomorrow

Can't believe some the lame answers here. Anyone having this issue check the PCV hose where it attaches too the air intake, the rubber breaks down and develops a leak. But these engines also have wiring issues that causes crankshaft sensor to fail at startup or under 1000 rpms causing the computer to shoot a code and trigger the engine light. I have these issue cause the above problem.

disconnect the battery for one hr.reconnect,if it still not ok,go to auto zone.they will tell you and give you printout of your problem.do not waste any more of your time.

The code indicates the battery at some point dropped below 9 volts, take your car to your local auto parts store and have them clear the code, check the battery and alternator. Most places they do this free of charge.

Trouble code P1633 means: Keep Alive Power Voltage Too Low

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?

p1633 is keep alive power voltage to low!! check voltage from alternator to battery, as well as all wires also.make sure battery terminals are not corroded. when car is running, voltage to battery should be 13.5 to14.5, when off voltage at battery should be 12.0 to 12.6,

without a fault code its impossible to diagnose. try pep boys or aamco or auto zone they will pull the code for you, usually for free. The code will relate to a sensor or area to be fixed. This will save you money and needless parts . post the code or codes so we can help
