1st try and search for a vaccum leak, due to the fact that these vehicles have had some bad problems with the length of wires and hoses, if there is a vaccum leak in the vehicle somewhere that will trigger other malfunctions in your vehicle. Using a can of starting fluid or Brake cleaner spray lightly spray around our engine til you hear the motor rev-up and the spot you have sprayed will determine where your vaccum leak will be. And then check under your distributor cap for any moisture be sure to take a rag and wipe and residue off. Also check the firing order on your distributor.

SOURCE: Check engine light is on, and OT sensor code is

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.
