If your car is less than 7 years old, dealer replaces at no charge (at least in Canada and I assume in the US as well). 1st dealer I called claimed this wasn't the case, but I called another and they were aware of the extended warranty service bulletin. No help here on how to actually replace it.

EGR valve is being cleaned due to "Check Engine"


CLEANING THE VALVE WILL NOT RESOLVE THE ISSUE, IT SHOULD BE REPLACED.

Took it to mechanic after it wont stay running he said it needs a crank shaft position sensor and egr valve. Where is the sensor and how do you replace it and how do you replace the egr valve.The mechanic...


what are the codes that made him think these two parts need replacing. The egr could cause a rough idle or stall, But it would need to be stuck open a little which may not set an egr code.

The crank sensor wouldnt cause a rough idle but the car could stall at times intermittantly.

What are you exact symptoms

Code p0406 dodge grand caravan 3.8 engine. Is it the EGR valve or the O2 sensor?


P406 is a EGR code, EGR will also cause a knocking/ pinging sound when there bad. Very common problem. The position sensor inside the valve goes bad. Your going to have to replace the whole EGR valve and it can put out variety of codes from P0401 to P0406. The new valve will solve the problem and easy to replace, you can pick one up at Auto Zone and they can give you the step by step instructions to replacing the EGR with common tools. Good luck and hope this helps.

How to remove egr valve on 1997 lincoln towncar


The EGR valve can be replaced by using a pipe wrench, or a standard wrench to remove the fitting over the pipe going into the EGR valve... it's not too hard to replace, I've done it on mine myself... I have a 97 town car as well... the only problem is that my EGR valve was fine, but the computer told me it was bad... But I found out that the EGR sensor was bad, not the valve... now to replace the EGR sensor you need to remove the engine... FORD in their infinite wisdom decided to put the EGR sensor on the rear of the engine, half way down next to the firewall...

My mechanic said that as long as the car is running fine, I souldnt worry about the EGR sensor, its job is to tell me when the EGR valve is bad...

Hope this helps
