P1633 gmc code I've a GMC Evoy with that code what that code mean

SOURCE: trouble code

please add the engine size in order to answer your question

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: wath P1406 Code means on a GMC jimmy 1996,

It's an egr valve problem (exhaust gas return) egr position sensor.
Take off the egr valve and turn it over and see if there is carbon build up in the ports, if there is clean it out with a pipe cleaner and a little carbon cleaner, just spray a little into the ports and clean it out. If that doesn't cure the problem, then either the sensor needs replacing, and or the egr valve.
