P-1494 LEAK DETECT PUMP SWITCH OR MECHANICAL FAULT

The most common cause for this code to set is a failure of the switch inside the leak detection pump. When this occurs, the pump needs to be replaced. The LDP is located in the right-rear side of engine compartment.

Code 1494


Did you mean p1494? If so then its your evaporative emission ventilation switch or a mechanical fault, probable causes:

  1. Evaporative Emission Ventilation Solenoid failed
  2. An open or short circuit.
  3. Vacuum hose clogged.
  4. PCM Failed
Check the following:

  1. Check the following connectors: A-109, B-76, B-63, A-107. Repair if needed. If its ok then check:
  2. Check the harness wire between the Evaporative Emission Ventilation Solenoid connector. If its ok then:
  3. Replace PCM

Code 1494


P1494 - LEAK DETECTION PUMP SWITCH OR MECHANICAL FAULT

When Monitored: Immediately after a cold start, with battery/ambient temperature between 40 deg. F and 90 deg. F and coolant temperature within 10 deg. F of battery/ambient.

Set Condition: The state of the switch does not change when the solenoid is energized.

This code sets when the LDP Switch does not close when the vacuum is let into the LDP. An evap leak will not set this code. First check the vacuum to the LDP. IF it is ok, you will need a wiring diagram to check the battery voltage, and the control wire, and the switch state wire to the LDP. If the wiring to the LDP is good, then the switch in the LDP is bad, and you replace the LDP. This is the case almost 100% of the time.

Good luck.

What is code 1494 mean for 2001 dodge neon


P1494 Leak Detection Pump Switch or Mechanical Fault
Part of the early evaporative emission system. (Fuel tank fumes)

It’s there to allow the computer to run an integrity test of the fuel tank, lines and carbon canister’s ability to contain all of the fumes coming from the tank and all line associated with the system.
The code could be set for a number of reasons such as a faulty gas cap, cracked vacuum lines, solenoids & vent valves stuck to the pump itself.
It can be a very difficult fault to cure being it doesn’t take a very big leak anywhere in the system to set the code and that’s if it’s a leak and not an electrical or mechanical fault.
