Hello,

My 94 E320 wagon won't start at all. I read the codes and got 8 (coolant temp sensor: open or short circuit) and 22 (camshaft position sensor signal defective). This happened at night by a Walmart, and had it towed to my mechanic. I usually investigate before I take it to the mechanic, but this time I won't be able to have the time to do it. But I'd like to sound educated when the mechanic calls me up. Can anybody tell me if these codes are serious to fix? What are they? Is it something DYI to fix it? How much would it cost to fix them?

Thanks a lot in advance,

Carlos.
