I'm still strugling with the P0401.
EGR is working, but vacuum on the valve and the engine wanted to die.
EVR is 34 ohms and is getting 12volts
DPFE however is getting 5 volts on the REF and Signal. Cold and warm engine.
According to the manual it should be 0.2-0.7 volts with cold engine but it's 5.0.
How does that effects the EGR??
when i disconnect the connector with ignition on "run" the REF and Signal are also 5.0 volts.
Bad PCM???
