P0420 and P0237 Codes 2005 c230
I pulled the following codes with my scanner:
P0420 Catalyst Efficiency Below Threshold Bank 1
P0237 Turbo/Super Boost Sensor A Circut Low Input
I also pulled the following engine info:
Coloant Temp 194
ST FTRM1 -3.1%
LT FTRM1 1.5%
MAP 9.7 in/Hg
RPM 753
Ign Adv 4.5 ~ 5.0
IAT 145
MAF .350 lb/min
ABSLT 1.9%
I have a 2005 C230 (M271 engine) with a Kleemann header installed. I also recently changed out both O2 Sensors.
Any info would be great!
