How harmful will it be to drive with a clogged EGR for a week or two. I just threw the 03 02 code, but can't fix it right away. Thanks.

 

Whats the 0302 code? Thats the knock sensor code. The EGR code is 1111. Its not that harmul to drive with a clogged EGR. Might be a little, but nothing to scratch your head over.

 

knock sensor is 03 04

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

 

mine was clogged for years, some say clogging up egr is good for performance, and maybe thats true ? in a hot climate a clogged egr could cause engine ping ?

 

My apologies. I didnt even look up the codes. I just used memory, which has numerous codes for 2 cars stored in it.

 

ha that's alright, I'll forgive you this time.

 

Check the how to's page 1..There's a title on how to troubleshoot EGR problems..My 0302 code went away after I replaced EGR solenoid valve.

 

how hard is it to replace the EGR Solenoide Valve, Because I got code 1005 and thats the problem ... also, How much does it cost ?
Thanks
