P1494 and p0340 codes on pt cruiser


p1494 = "Evap leak detection pump pressure switch"
p0340 = "Camshaft position sensor"

You have two unrelated problems. The computer doesn't like your cam position sensor - replace that sensor. There also seems to be a problem with your evac pump, which may be a lot harder to track down; you may have a problem with the pressure switch or with a vacuum leak or vent leak somewhere within the fuel-tank-to-charcoal-canister-to-engine lines. Try replacing that switch first. If that doesn't fix the problem, then you'll need a hose routing diagram - with it, trace the vacuum lines and vent lines, looking for leaks or blockages.

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).

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.

This code is caused by the leak detection pump for the evaporative emissions control system, this is a common fault in your year and model, there are factory bullentins about the code, to replace the pump do the following. As noted in the procedure pay close attention to the condition of the vacuum lines to the pump.


The LDP, (leak detection pump) is located in the left/front corner of engine compartment below the air cleaner housing. It is mounted to left/front inner fender sheet metal. The LDP and LDP filter are replaced (serviced) as one unit.
