2005 srt-4
Haveing non stop problems with the ecu code
p2074 turn it off comes right back
pleas help me !!!!!!!!!!

Thats an Intake Manifold Tuning Valve code. Since it comes back, I'd bet theres actually something wrong with the valve.

It does not come on at idle only when half throttle or part thottle
runes good at wot. It all starded when I put the thrttole body on ???

Is the SRT4 Drive By Wire? Probably needs to be calibrated if it is.

I don't think it is drive by wire it has a cable to the thottle body

Stick to newb Hemi questions mike.

1) SRT-4 do not have a Manifold Tune valve

2) SRT-4 have a throttle cable.

3) On a SRT-4, P2074 is for MANIFOLD PRESSURE/THROTTLE POSITION CORRELATION- HIGH FLOW/VACUUM LEAK

its a not too uncommon code with aftermarket wga and bov, especially with 2005s. There's actually a Factory TSB for this code for 2005s. http://www.ertyu.org/steven_nikkel/neon ... 042-04.pdf

PCM boost control and a properly scaled Wastegate Duty cycle table to match your uber stiff wga, this code isn't much of an issue.

imo stiff wga aren't worth the trouble over the stock wga if you have a stock turbo.

If it all started with the TB, your TPS voltage may be off

I'm reading straight from the Dodge Codes thread. Thats where my info came from.

Thats also why I asked if it was DBW.

I've been begging DS to find the switch that disables this code as it is a major issue. The stage cals already have this diagnostic feature disabled so if you continue to have problems I suggest upgrading to a S2 PCM.

Thanks going to s2 PCM hope it works
