Question: 1999 Dodge Intrepid 139,000 3.2 V6 Battery and starter put on a month ago. code P1494 came up when i had it reset and 2 days later it came back on. what do i need to replace and will it hurt if i continue to drive it for a little while before i can get it fixed? - Rick, September 2008

Answer: Hi Rick. 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.

Question: Hey I have a 2002 chrysler neon, Its all stock and has never given me any grief and then today I got a engine light the code is P0194 Fuel Rail Pressure Sensor Circuit Intermittent, The car still runs good, I just would like to know some of the possible causes, as I dont want my car to run lean and blow up lol. Thanks any information would be helpful - Paul, September 2008

Answer: Hi Paul. Funny thing the Neon was a Chrysler product in Canada in 2002 and a Dodge model in the US. The P0194 code refers to the electrical part of the Fuel Pressure Sensor Circuit. Since it's intermittent it could mean that the sensor itself is failing/failed, however I suspect the more likely culprit is a problem with the wiring and/or connectors. Check all wiring & connectors leading to/from the fuel pressure sensor, look for any visible frays, shorts, etc. If you're eager you may want to also verify the correct specifications on the sensor, or trace the wires to determine if there's a short. Good luck!

Question: HAVE A 2000 DODGE DURANGO . CHECK ENGINE LIGHT IS ON AND I WENT TO AUTO ZONE . THEY TESTED IT AND THE READER SAID THERE WAS NO TRUBLE .THEY TRYED TO TURN OFF THE ENGINE LIGHT BUT COULD NOT IT JUST CAME UP WITH ERROR . COULD NOT TSLL OR DO ANY THING .I TRYED SEVERAL THINGS BUT COULD NOT TURN OFF THE LIGHT . CAN YOU HELP ? - Larry, August 2008

Answer: Hi Larry, thanks for the question. It seems to me that the code reader is not able to connect to the Durango's computer. I've seen this many times before. I would recommend you try another code reader, see if it's able to see the codes. If not then it's likely a communication problem. The most common fix is to check and replace the fuse as necessary. It's usually the cigarette lighter fuse that also controls the OBD-II port. Check that fuse, in fact, check all the fuses on the truck. Good luck!
