SOURCE: 97 mitsubishi eclipse transmission problems automatic 2.0

I have a 95 Eclipse and I recently had to change out my TCU........ Transmission Control Unit, This should be located directly beneath the center console. First I would have the transmission services if problem persist then proceed to changing out the TCU you can get off of ebay. As far as i know there should be 3 Computers in our cars. 1 the Electronic Control Unit located behind radio 2 Transmission Control Unit located under center console and 3 Airbag Control Unit located under hood, Hope this helps.

SOURCE: somg check problem (code p1494)

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.

Start with the easiest, look at your fuel cap. Is the gasket good? Buy a new one, clean where it seats well, put it on making sure it clicks at least 3 times, and see if that solves it. If not you will have to start looking at hoses for hairline cracks. And yes, although it's rare, sometimes the canister itself gets a crack and needs to be replaced. It will be a dealer only item of course

Answer
Hi ,
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. According to a Chrysler manual I have, you would find the pump, probably on the underside of the vehicle by tracing the hoses related to the vapor recovery tank that may be in the right front corner of the engine compartment (I don't know Jeep designs) and then check to see if the pump starts when you turn the ignition to the run position when the vehicle is cold. Then remove the vacuum hose side of the pump and see if it draws a vacuum. If it does, then the vacuum-detecting switch that detects that the pump operation is OK may be faulty. If the pump doesn't start or doesn't draw a vacuum then the power to the pump, the pump itself, or the vacuum line may be leaky. Finally, the powertrain controller could be at fault.
In any case, that is where the issue is, and it should not be a major issue if it is handled by a knowledgeable mechanic. But you could check it over yourself if you are so inclined. p.s. your best bet is to take it to a jeep dealer to get it fixed hope this helps please dont forget to rate my solution

For more information see if you can get a copy of this Technical Service Bulletin from your local Mitsubishi dealer.

NO.: TSB-98-13-012
DATE: September, 1998
MODEL: 1996-97 Eclipse 2.0L Non-Turbo

SUBJECT:
Evaporative Emission Control Leak Detection System Diagnosis

PURPOSE:
This bulletin describes the operation of the evaporative emission control leak detection system and how to diagnose diagnostic trouble codes (DTCs) relevant to this system (DTCs 183, 184, 187, 160, and 161).

I think the whine you hear while turning the steering wheel is a P/S system that's low on fluid or a P/S pump starting to go bad.

The rattle under the dash could be anything from loose change to a loose component.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I have a 1999 mitsubishi eclipse with the stock 420a (non-turbo) engine. The check engine light turner on with two codes, p1494 and p1495. I fixed p1294 but still have no clue what p1495 is or how to fix...


I kept getting this code on my 2001 stratus it had the 3.0. The problem for me was my egr valve. I was able to clean mine with card cleaner and it worked for me. But every six months it came back and had to clean it again. Later found out I had some vacuum leaks which were causing car to run rich as cause more junk to clog egr. After fixing those the problem stopped. Good luck.

My service engine soon light is on and I have been told the code is 1494. What does that mean?


P1494 is a Leak Detection Pump Switch or Mechanical Fault. 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). This is a problem with evaporative emissions system and should not affect drivability. If this was helpful please leave positive rating.

If you turn the ignition on does the check engine light come on for a few seconds and then shut off? If it doesn't, perhaps the bulb is burnt out or a previous owner removed the bulb?

MItsubishi Eclipse p1494 code


P1494 code can cause by EGR lift sensor.

When the engine is cold,disconnect the EGR sensor connector and clean the contacts.

Reconnect the EGR connector and reset code.

================

If the code does come back then I will clean the carbon under the EGR valve (or replace it)/
the EGR air passage MUST be clean also.

Please order a EGR base gasket before you start this job.

It's very time consuming but it preventive you must do.

This should free up the movement on the EGR.


I will ran a FULL TANK of Chevron gas to clean out the injector also.


Reset the code and you should be fine.


Please post more information on the comment window.
