My 2010 navara has broken down and come up with the faults PO403 EGR system and P0089 fuel pump, what's the most likely problem? It's lost all power and blowing smoke out.

code p 0403 refers to exhaust system gas recirculation (EGR)---circuit malfunction====causes wiring---EGR solenoid ---ECM
code p 0089 refers to fuel pressure regulator---performance problem===causes fuel pressure regulator---mechanical fault
as you indicate smoke , that would be black smoke , so that indicates a problem in the pressure regulation making the injectors pass more fuel ( flooding) than the ECM cam control
The end result can be blown seals at the injectors or injector problems
at this point replace the pressure regulator, then consider the EGR solenoid

Been Diagnosed from the rac with egr probs

code p 0403 refers to EGR --circuit malfunction===causes --wiring---EGR solenoid --ECM
replacing the valve probably not the problem as there is a separate solenoid to work the valve and that is what is listed in the probable causes
then you have to consider the wiring and connections to the unit

OBD-11 codes 0403 & 0405

code p0403 refers to EGR --circuit malfunction===causes ---wiring--EGR solenoid---ECM
code p0405 refers to EGR valve position sensor A --low input===causes ---wiring ---short to ground---EGRF valve position sensor--- ECM.
By only changing the EGR valve you have not fixed the problems that cause the valve not to work.

Get code P0403 on 2001 Dodge Caravan...even after I just replaced the EGR valve twice (first replaced as thought might be faulty) cleared a few other codes related to EGR flow, but the P0403 ke

if you have a obd11 scanner, clear the codes and drive the vehicule for a while ,a good half an hour or so above 30 mph. this will give your onboard computer a chance to relearn system settings.if the code comes back there could be some other sensor malfunctioning or a problem with the onboard computer.ex corroded connections or broken pins.

Ok I have a 2001 chrysler sebring lxi coupe with 3.0 mitsubishi engine and just about replaced everything including having transmission rebuilt and now showing code for egr monitoring sensor problem is...

Throwing new parts at a car in response to fault codes in the vague hope it will provide a cure is not the best or the cheapest way to proceed.

Nothing should be replaced unless it can be justified by independent testing. A code reader is not an oracle and the results can be misleading. A fault code is merely the first step of a diagnosis process that is verified or rejected using live data from a scanner, oscilloscope checks, multimeter checks and a deal of experience.

It is often false economy not to pay for a high level of expertise from the start. Paying for skill and experience is often cheaper than a host of unnecessary new parts.

Hi, a P1684 is "Battery Disconnected Within Last 50 Starts". I wouldn't worry about that too much.

The P0340 is "Camshaft Position Sensor Circuit Malfunction". I'd definitely look into that code. I found a great article specific to the p0340 code - - it should give you an idea on what to look for, test, replace, etc. Good luck!

2001 sebring will turn over but will not start

Most Chrysler cars do have an anti-theft system that can cut out the engine.

I would call the service department, with your VIN handy, and see if yours was equipped with one, and what you need to reset it.

If that isn't the problem, your EGR valve might be bad, or the sensor for it. I've seen a lot of cars where if either the valve itself, or the sensor are malfunctioning, the car won't run properly.

I would also check your MAF and IAC, as those can cause the car to not run.

If you can, get an OBDII code scanner, and pull the codes from your car, they might give you a more specific place to look. (Most parts stores will let you take one home, you put a deposit down, and get it back when you bringthe scanner back to them)
