So this is a follow up to my previous post about EGR and turbo issues.
I've got a 2007 Dodge Sprinter 170" WB. -- 55,000 miles
I've had intermittent issues going into limp mode. I plan on changing the 2 intercooler hoses along with the intake air sensor and cleaning the EGR but it's too cold here in chicago without a garage.
Codes I've retrieved in the past are P0234 (turbocharger/superbooster overboost condition), P0471 (exhaust pressure sensor a circuit range/performance), P0473 (exhaust pressure sensor a circuit high input).
I had a rusted tail pipe right after the muffler that had been disconnected, just had that fixed yesterday
I had this scanned with the MB scan tool and was told i needed a new turbo because the actuator or regulator was bad.
Mind you , these are intermittent issues.
Latest code i retrieved a few days ago was P0234. Here's the freeze data:
Abslt TPS% 80.8
Eng Speed 2143
Baro Press 28.3
Calc Load 48.2
MAF 111.26
MAP 58.2
Out Temp 41
Coolant 120
IAT 64
VEH Speed 31 mph
ABS FRP 9127.22
REL TPS 12.9
THROT CMD 85.9
ACC POS D 29.0
ACC POS E 29.0
EGR ERR -23.4
EGR CMD 32.6
FUEL 53.7
VPWR 12.98
How do you know if something is wrong with the EGR valve (i.e. dirty) or if it's truly a bad turbo regulator? Should the EGR err% be 0 ? I'd appreciate any help. Thanks.
