Tengo una dodge caravan motor 3.3 - cuando el motor lleva cierto tiempo funcionando pierde fuerza. lo escanearon y da el codigo P1494.(el motor esta recien reparado)y antes de repararlo no presentaba la...

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:

SUBJECT: Misdiagnosed Leak Detection Pump Systems With DTC P1494, P0442, P0455, OR P0456.
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.

Traduccion automatica:
El Dodge motor P1494 c?digo de luces de detecci?n de fugas de la bomba o el interruptor de falla mec?nica. Un diagn?stico correcto se debe hacer, no se puede simplemente sustituir el PLD y esperamos que para solucionar el problema. No debe doler nada que mantener la conducci?n por un tiempo hasta que te lo arreglen.

Hay un bolet?n de servicio t?cnico que se aplica a su veh?culo y se menciona que el c?digo en particular. Lo incluyo aqu? para su informaci?n:


Diagnosticado de fugas Sistemas de detecci?n de la bomba con DTC P1494, P0442, P0455, P0456 O.

1997 - 2000 (LH) Concorde/Intrepid/LHS/300M/Vision y otros!

Durante el diagn?stico del sistema de evaporaci?n, de detecci?n de fugas bombas han sido sustituidas por error. Una inspecci?n minuciosa de las l?neas de vac?o pellizcar, torcer o desconectado de suministro (en la actualidad figuran en los Procedimientos de Tren Motriz de diagn?stico) es un paso cr?tico en el diagn?stico de DTC P1494 (PDL SW O AVER?A MEC?NICA). Adem?s, los otros fallos por evaporaci?n de fugas (DTC P0442 - peque?a fuga, P0455 - fuga grande, y P0456 - MUY PEQUE?OS DE FUGAS) deben tener las l?neas de alimentaci?n de vac?o examinados por pellizcos o vueltas antes de cualquier reemplazo de componentes del PLD. Las l?neas de alimentaci?n de vac?o se debe revisar el compartimiento del motor hasta llegar al tanque de combustible, incluyendo el PLD y el sistema de purga.

NOTA: VERIFICAR todo lo relacionado SUMINISTRO DE RUTAS l?nea de vac?o PIZCAS, torceduras, o desconexi?n ANTES DE CAMBIAR LOS COMPONENTES DEL SISTEMA PLD.

Check engine light is on, and OT sensor code is P1494 was diagnosed.

P1494 - LEAK DETECTION PUMP SWITCH OR MECHANICAL FAULT . There is a service bulletin for certain years pertaining to this problem . Some cars will fill the vacuum line going to the LDP with oil , causing this dtc to trip . In most cases you can clear this and it won't come back-also, check your gas cap, it needs to seal the system, if it is loose or leaks, it can set this code.

Dodge dakota vacume problem

You need a diagnostic box to tell you what the problem is.......if it is a evap leak,it could be anywhere,the hoses,the gas tank seal,a cracked hose.If you can go to a dealer they might have a smoke machine, they watch to see where white smoke is escaping from.Which is impossible to tell other wise. Could even have over filled the gas tank,that would give you an engine light......

Diagnostic error code

The code refers to the leak detection pump that is part of the gasoline vapor control system which is for pollution minimization. It says either that the pump switch or mechanical operation is faulty. I had this happen on a 2000 Dodge Dakota and a replacement Gas Cap fixed the problem. A faulty gas cap seal can also cause this.

Good luck
