It could mean a few things but a safe bet would be to replace the EGR valve as it may have become faulty.

Trouble code p0106


Code 106 is for a problem with the signal coming from the MAP sensor, not the EGR valve. The MAP sensor and circuits would need to be checked.

someone removed the egr. or someone replaced the engine with a non egr engine. if the engine was changed you ether need to put an egr system on it or change the computer with one made for an egr exempt engine.

The computer on the truck says to have maintenance performed. Checking the owners manual, it says the EGR valve needs to be replaced. Where is the EGR valve, what does it do and where do I get the part?...


Are you sure that the Owners Manual is telling you to replace your EGR Valve or is it simply telling you to check it? Does the light on the dash say "Maintenance Required"? or is your Check Engine light on? If your vehicle is equipped with "Maintenance Required" light, the vehicle usually does not need anything. You simply check the systems that are listed by the manufacturer to check, make repairs only as necessary, and reset the light. Chrysler did some goofy stuff with Maintenance Required lights back in the 80's where they recommended replacemet of a whole bunch of parts that the vehicle didn't need to have replaced. We used to just reset the light and send the vehicle back to the customer. I haven't seen one of those for a while. If your 2007 has one of these, it means Chrysler is up to some old stuff for 2007.
On the other hand, if it is the "Check Engine" light that is on, the computer needs to be scanned for fault codes and diagnosed and repaired accordingly. Also EGR valve failures are pretty rare. When the Engine Computer sets a fault code for the EGR system it usually is not caused by the EGR Valve itself. Your 2007 is OBDII compatible, which means if you are having a problem with your EGR System the Check Engine light will be on and fault codes will be stored in the Engine Computer.

The engine light on our 1986 Mercury Grand Marquis came on and stayed on. When checked, a code of 34 comes on. What does this code mean?


code 34 means you are not getting any egr flow. find your egr valve and check to see if vacume hose is attached, if so follow the hose to the egr solenoid which should have that hose and a direct vac hose going to it. and an electrical connector. make sure all of these things are in place and not disconected or broken. the most likely cause is either a broken vacume hose or a clogged intake manifold.

I have a 97 Ford F150 that has had a check engine light on for the past 3 years. Everytime and I mean everytime they do a diagnostic they tell me it is the O2 Sensor then the EGR - well I replaced them...


I had a similar problem with my 97 f150 4.6L. I work on it myself and after continuous check engine light with an EGR insufficient flow I replaced all 3 EGR components. (EGR valve, DTFP, and EVR regulator) Still got EGR insuffiecient flow. This Saturday I took the throttle body off (has the ports that EGR flows through) and WhaLaa!! It was totally, and I mean TOTALLY clogged with tar and gunk from the exhaust. 3 hours to clean it out and soak it and clean it all up. Fixed the problem, 300 miles later and it's still good with no codes. I have my own code reader so it made it easy to check sensors. All read "OK" now. It was worth the 5 hrs spent taking it apart and reassembling. I changed spark plugs and PCV too!! Good luck. You can do it yourself If you tell yourself you can.

2002 Crown Victoria check engine light stays on


also have them change the oxygen sensors, if it's deemed necessary. have someone reset the computer. if the light stays off, then you don't have to.

Check Engine Light


sounds like you have a code for evap leak detected. thats why you have been told to change the gas cap. this means you have a vapour leak in your systam. check all line and hoses to and from gas tank for leak. the filler hose and lines may be leaking. good luck please rate this.

Check Engine Light Code 332


332 = EGR valve opening not detected.

You should be able to find a list of DTC's on the Internets somewhere.
