SOURCE: 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.

SOURCE: 1998 dodge ram error code 1494 check engine light

Check all tubing and junctions for leaks in the fuel evaporation control system. The ECU has detected an issue with intake manifold pressure and is indicating that fuel vapour recovery system is perhaps to blame. Sometimes this can be connected to a fault in the manifold differential pressure circuit which lies on the vacuum line leading to the EGR valve. Also quickly check that the EGR (exhaust gas recirculation) valve is OK by connecting and reconnecting its vacuum line and listening to engine note changes. No engine note change indicates the EGR is probably jammed shut with exhaust crud and needs a general clean up. Sometime these codes detect the symptom and not the cause so you just have to work your way back and eliminate what it might be.

SOURCE: I have a 2008

P0489-egr Control Circuit Low
P042E - EGR Control Stuck Open

So when the engine is cold, feel the EGR valve.
They start it up.
At idle it should stay cold.
It is heats up quickly, then the EGR is open at idle, and it should not be.
It is probably manually binding from exhaust deposits.
It can be cleaned with a wire brush or chemicals.

If that does not work, you can just block it off.
EGR is not good for any engine, because it causes deposits on the back of the valves. But it is necessary on some high compression engines, in order to poison the mixture enough to prevent predetonation. But a diesel can never have predetonation, so the EGR is totally negative and should be removed for optimal life span.

04 dodge ram pickup has code po 456 what is this code? 04 dodge ram 1500 5.7 engine gas mileage has gotten worse.


Small leak in evaporative emissions system. Basically takes fuel vapors and recirculates them back to engine to be burned rather than vented into the atmosphere.One common cause of light on dash is faulty/dirty gas cap seal. Did you add fuel just before light came on? Otherwise a small leak at a hose etc., in system, as well as faulty purge system may also cause it.

I have a 200 ram 1500 4x4 and i pulled some codes off of it last night, and they said that the 2 of the injector circuits were malfunctioning and also gave me a dtc 1494 whatever that is! the truck runs...


if its white smoke then its a head gasket ,if this is the case then this is why you are getting the 2 injector codes and if these two injectores are next to each other then its blowing between two pistons
