Hey everyone,

I'm getting the 0704 DTC (evap emission control system pressure sensor) but what's really weird is that the day before I got this code, my Max was really hard to start. I've read in the FAQ that this sensor does not control engine operating parameters so why would this cause the hard-start condition?

I should also mention that before the MIL light came on, the engine was hard to start. After the MIL light came on, the engine starts like normal. I assume the ECM is in fail-safe mode. But why for the 0704?????

Anyone have this prob before?
