U will need to drive a mixture of stop and go, city low speed and freeway miles, this can take a week and 20-50 miles or so for the system to finish it's internal self testing. this is called a drive cycle test.

1999 dodge durango oxygen sensors do notm correct Check Engine Light. Have been told there was a different harness available from Dodge also that an internal vacuum leak can cause this.


have the fault codes read
as the engine light also reports on transmission problems as well as the engine
changing oxygen sensors (O2) will not fix the problem as there is an heated oxygen sensor (HO2S) in the exhaust manifold that controls the air/fuel ration settings and that is affected by a vacuum /exhaust leak

2004 Dodge Durango 4.7 liter started then just stopped will crank could be fuel line freeze up.Also told could be Cam shaft senor Crank shaft sensor had check engine light on did OBD said EVAP Leak


Suggest before you start to replace parts See what is missing , fuel or spark . Evap leak has nothing to do with it . Videos on youtube testing spark and fuel pressure . special tools needed . You probably would be better off just taking it to a qualified repair shop that has all the tools . Probably know in less then an hour what's wrong .

Engine shut off while towing up a hill.


You'll need to have the computer scanned for trouble codes then go from there. If the check engine light was on for more than a minute there should be trouble codes stored.
The EVAP leak would not cause the engine to stall.

An evap code p0456 small leak already changed the gas cap looked at all rubber hoses and lines found nothing never smell any gas 02 durango sxt


First, using a scan tool activate the vent solenoid, sealing the system. Then monitor the fuel tank pressure (FTP) sensor. If the system is sealing properly, the number will stay consistent. If is isn't, the pressure sensor will show that as well. If the system slowly leaks, use a smoke machine and watch for smoke exiting the system at any EVAP component. Any where there is smoke exiting the system, that is the faulty component. Do not pressurize the EVAP system with air pressure. Doing so can damage the purge and vent solenoids in the system.

2002 dodge durango engine light on. after diagnostic test.results indicate evaporator hoses are leaking


Check your gas cap first.

Replace the cap and have the code cleared at Autozone. If the problem comes back, look for cracks in the lines between the gas tank and the evap canister behind the battery.

Dodge Durango code shows 0051: where is Sensor 1/Bank 2? Where can I find a pix or diagram? Code also showsP0700 & P0455; what do these mean? Thanks.


Bank 1 is the same side of the engine as the number one cylinder. Bank 2 is the other side of the engine. Sensor one is always before the catalytic converter. Sensor 2 is always after the catalytic converter.

P0455 is an EVAP leak check the evap hoses for cracks/leaks.

P0700 is a generic code that lets you know you need to scan the transmission control module to see what codes are stored in it.

Do you know how to test electrical circuits ? Is the PCM - engine computer controlling the coils ? Test with a test light ! One side has B+ voltage the dark green with orange stripe wire ,the other goes to the PCM , which will suppy a ground when triggered . You can test this with a test light . or you can buy a noid light at the parts store . If you replaced the coil an spark plug an that code comes back ,could have a burnt driver inside the computer , test it first !

On dodge durango and chrystler check engine light came on...after fueling..how do you get light off???


it sounds like you left the gas cap off after filling the tank. the computer sensed a "large" evaporative leak in the fuel evap system and turned the check engine light on. just by putting the cap back on wont turn the light off right away, but the computer WILL reset (turn the light off) after the next time the computer runs the "evaporator" function test. it might take upto 3 days, but it will reset. If it doesn't reset after 3-5 days you may have a different propblem. Some auto part stores will scan your computer for codes and try to sell you parts. At least this will tell what code you have and how important it is to fix it.
Hope this helps.

Evap system errors, cylinder misfires....


it is VERY common for the gas cap seals to go bad and cause an EVAP leak that generates a code.. i have seen alot of this in recent years, these cars now have pressurized systems....good luck! it could be a quick and cheap repair!
