1994 E420 Code4 and Code19
Hi,
I did the research on code 19 and know about the chip that Jim has. My questions is that I recently replaced the pipes going to and from the check valve on top of the air pump. Could this cause me to get code 19? Also when the check engine light came on I read the codes from the push button first and got code 4 and code 19. Then I read the codes at pin 4 got back a 1, pin 6 got back a 1, pin 7 got back a 6, and pin 19 got nothing. Is this normal for pin 19? I thought I should have gotten something. What causes code 6 at pin 7? I keep getting this code on that pin. Is there an easier way to clear the codes on all the modules at once? Thank you. |
