$400 For An 0302 Code Fix?!!
My dealer just called me back and says they need to drop a frame member to access the EGR tubes for cleaning to remedy my CEL... Cost? ~$400.00.
I was anticipating about $150.00 but not $400.00!.

That's a bunch of crap...they can get to it by removing the air filter and a few other upper parts. I changed mine and the hardest part was removing the nut that connects to the EGR itself. Before you replace it check to see if the small rubber hose connected to the EGR valve has not come loose at either end. The valve costs about $133 from the dealer and should only take about 45 mins to replace.

0302
Diagnostic Trouble code 0302 points to a problem with the Exhaust Gas Recirculation system. The malfunction is detected by the Engine Control Module when no EGR flow is detected under conditions which call for EGR. Possible causes include:
- The electrical harness or connectors (valve circuit open or shorted)
- The EGR valve is stuck closed
- Weak or dead battery
- The EGR passage is clogged
- Faulty EGR temperature sensor circuit
- A leak somewhere in the exhaust system
The EGR Volume Control Valve may be tested with an ohmmeter. Disconnect the electrical connector. Looking at the connector half which is attached to the EGRVCV with the latch at the 12 o'clock position you will see two rows of three terminals. The top row is numbered 1-3, right to left. The bottom row is numbered 4-6, right to left. Measure the resistance between these terminal pairs:
2 1
2 3
5 4
5 6
... all resistance values should be 20.9-23.1 ohms at 68 degrees F.
Reconnect the EGRVCV connector halves. Turn the ignition switch ON OFF repeatedly. Verify that the EGRVCV shaft moves smoothly forward backward according to the ignition switch position.
The Exhaust Gas Temperature Sensor may be tested with an ohmmeter. The specifications are ...
- at 32 degrees F, 0.68-1.11 Megohms
- at 122 degrees F, 0.09-0.12 Megohms
- at 212 degrees F, 0.017-0.024 Megohms

What are the symtoms with a faulty EGR system?
I have had problems with starting the past few days and when I finally got it started there was what looked and smelled like exhaust coming from around the throttle body. It seems to be starting and running fine now that I finally did get it started.
