Fixed Blown Head Gasket. Need help clearing Code

sXericerider · Sep 29, 2009, 08:15 PM

So after a 5 month slump of finally getting to get my car running from a blown head gasket, my mechanic finished working on it yesterday and got it running. I have to get it smogged, but its throwing a CEL code P0441 -Evaporative Emission Control System Incorrect Purge Flow. Researched about it and it said something about the EVAP system. Tried to get the mechanic to work on it but his job was only to work on the head and the head gasket and wasn't willing to look into it.

It said online that one of the main reasons could be the gas cap and I checked it and it was closed. Any other suggestions to try and help would be great. Also it said something about a purge solenoid and idk where that is.

a line is off or leaking. Do you smell gas?

Theres still a bit of smoke after 10 mins of idle. When i reset the code its fine in idle but when i try to rev to 2k rpm it throws off the code. There's a smell coming but im not sure if from the burnt oil from right when the head gasket blew or gasoline

It might also be some lose hoses. I'll try to recheck those again.

Whoa red hot for real??? Thats not good bro you watching your engine temps? Have you checked the coolant and oil levels? How reliable is the mechanic? No offense but it sounds like the dude might be afraid he did something wrong and doesnt want to discover it checking into your problem. I know a couple people like that, they will do a job and then something isnt quite right and they tell the customer that exact same line and I know its due to them scared that they messed something else up. I have worked on hundreds of cars just around my town and anytime there is another issue right after I get done I make sure and get over right away to get it solved. Again not saying this is the case and/or trying to put down your mechanic. It sounds like he either reversed some hoses somewhere or missed some altogether. Check every hose going into your intake manifold for cracks, breaks or any nipples with no hose attached. Was this issue there before the blown head gasket? I can only assume not. Also follow those same hoses coming off your intake manifold and make sure they are all connected.

Here is from the FSM
1. Disconnect the purge hose from the evaporative emission
(EVAP) purge solenoid, and connect special tool MB995061
between the EVAP purge solenoid and the purge hose.
2. Before inspection and adjustment, set the vehicle in the
following conditions:
• Engine coolant temperature: 80 − 95°C (176 − 203°F)
• Lights, electric cooling fan and accessories: OFF
• Transaxle: Neutral (A/T − P range)
3. Run the engine at idle for more than four minutes.
4. Check the purge flow volume when engine is revved
suddenly several times.
Standard value: Momentarily 20 cm3/s (2.5 SCFH) or
more.
5. If the purge flow volume is less than the standard value,
check it again with the vacuum hose disconnected from the
EVAP canister. If the purge flow volume is less than the
standard value, check the vacuum port and the vacuum
hose for clogging. Also check the evaporative emission
purge solenoid. If the purge flow volume is at the standard
value, replace the EVAP canister.

EVAPORATIVE EMISSION PURGE SOLENOID
CHECK M1173001700104
1. Disconnect the vacuum hose (black, black with red paint
mark) from the EVAP purge solenoid.
NOTE: When disconnecting the vacuum hose, always place
an identification mark so that it can be reconnected at its
original position.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the EVAP
purge solenoid (refer to the illustration at left).
4. As described in the chart below, check airtightness by
applying a vacuum with voltage applied directly from the
battery to the EVAP purge solenoid valve and without
applying voltage.
5. Measure the resistance between the terminals of the EVAP
purge solenoid.
Standard value: 30 − 34 Ω [at 20°C (68°F)]
6. Replace solenoid if resistance is out of specification.

Hope this helps!!
