Code p1494 grand laredo cherokee 2001


Here is the definition.
You'll need a shop manual for the procedures.

P1494 JEEP Description The Evaporative emissions system is designed to prevent the escape of fuel vapors from the fuel system. Leaks in the system, can allow vapors to escape into the atmosphere. The leak detection system tests for EVAP system leaks and blockage.


During the self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LD pump to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

I need a fuse diagram, so I know where the fuses go


You might try the online discussion groups for Jeeps. A Haynes manual would have the wiring diagrams but I don't know about a fuse layout. The owners manual would have it if you could find one on Ebay.

What does white smoke from hood and sluggy dipstick mean?


That likely means that you've blown a Head Gasket. Don't drive the car any further. You can seriously damage the engine. You'll need some pretty serious engine work done. So, ask around for a reputable mechanic that knows how to rebuild engines or can install a replacement engine if needed.

Bound to be online, somewhere. Google "jeep fuse box diagram". I found a 96 grand cherokee diagram in just a moment's search. Many, many pages there. Also jeep forums, 4wd.com; libraries are an excellent source also, if you can find the right repair manual. Good luck.

2001 jeep cherokee has a p1494 code and a p0301 code seems to be running fine but want pass emissions


0301 is cyclinder 1 miss fire,check coil pack and spark plug,plug first,1494 is the fan relay,It's in the right front of the engine compartment. Kind of behind and below the RF headlamp and in front of and below the fuse box.
Easy to replace, just unplug it and plug the new one in.
The relay is the most common cause for that code with a no fan operation condition, we see it all the time.
