SOURCE: 01 dodge ram 1500 5.2 4WD code P0455 evap system leak.

This code will not stall or no start of your engine, evap only work when engine is off, it is to reduce the fume your gas tank lets out to protect the o zone, but it will not pass Emission test, also could be some thing a small as your gas cap not sealing right.

Code p1494


Hi there:DTC P1494 - Leak detection pump pressure switch or mechanical fault

That code indicates a problem with the fuel evaporative system test pump, either a power or line leak. If the pump runs, check the lines going back to the tank and make sure everything is connected and ok.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Engine light stays on code p1494


P1494 code is a leak detection pump switch or mechanical fault, leak detection pump switch does not respond to input. The leak detection pump (if equipped) is located under the air filter housing on models through 2001. Check if the vapor and vacuum lines are securely connected to the leak detection pump or a diagonstic trouble code my be set like this. The leak detection pump switch may be bad and need replaced.

P1494


The Dodge P1494 engine light code means Leak Detection Pump Switch or Mechanical Fault. A proper diagnosis must be done, you can't simply replace the LDP and expect that to fix the problem. It shouldn't hurt anything to keep driving it for a while until you can get it fixed.
There is a technical service bulletin that applies to your vehicle and it mentions that code specifically. I'm including it here for your information: TSB-18-01-00
SUBJECT: Misdiagnosed Leak Detection Pump Systems With DTC P1494, P0442, P0455, OR P0456.
MODELS: 1997 - 2000 (LH) Concorde/Intrepid/LHS/300M/Vision and others
DISCUSSION:
During evaporative system diagnosis, Leak Detection Pumps have mistakenly been replaced. A thorough inspection for pinched, kinked, or disconnected supply vacuum lines (as currently listed in the Powertrain Diagnostic Procedures) is a critical step in diagnosing DTC P1494 (LDP SW OR MECHANICAL FAULT). Additionally, the other evaporative leak faults (DTC P0442 - SMALL LEAK, P0455 - LARGE LEAK, and P0456 - VERY SMALL LEAK) should have the supply vacuum lines examined for pinches or kinks prior to any LDP component replacement. The supply vacuum lines should be checked from the engine compartment all the way to the fuel tank, including the LDP and purge system.

NOTE: VERIFY ALL RELATED SUPPLY VACUUM LINE ROUTINGS FOR PINCHES, KINKS, OR DISCONNECTION'S BEFORE REPLACING LDP SYSTEM COMPONENTS.

Hope helps (remember rated and comment this).
