Deciphering Codes OBD2

Deciphering Codes OBD2
Having some problems. This is the beginning of the saga. First the car began to sputter and RPM’s fluctuating rhythmically turned off car, as it never shut down on it own. Pulled codes before turning car on again at same location with OBD II actron scanner. Codes read P0172 system to rich bank 1, & P1017 manufacturer specific DTC. Erased codes opened hood noticed with engine and key off the secondary air injection pump was humming/vibrating a very small amount when the power was disconnected from unit it stopped. Removed the air box, MAF, and secondary air injection pump. Cleaned and lubricated all applicable parts i.e. MAF with contact cleaner, and the air pump with contact cleaner and lubricant. Also checked all Vacuum lines out of air box and zipped tied them so as to not have leakage. Reassembled and started vehicle no problems although the secondary air injection pump still vibrated a small amount with engine off. Drove vehicle for a few days then got a P0171 to lean bank 1. Also have noticed the engine starts hard now and it shuts down hard not like it used to and the RPM’s fluctuate from 1100-1200 at first startup then drop to about 900. Anybody have similar experience?

It could very well be a bad throttle body. The Manf. code you had most of the time is a throttle body code.
Try to drive it a little more and get that code back in there. Then take it to the dealer. If it is the throttle body they will replace it for free under the new warranty 10 years 200,000 miles.

RE: Deciphering Codes OBD2
OK here are the codes I came up with.
P1008/1009 = ETS light
P1019/1020 = Throttle body communication
P1021/1022 = Throttle unit
P1026/1027/1028/1031/1032/1033/1053 = throttle body internal fault
P1029/1030/1042/1043/1044/1052/1055 = accelerator pedal sensor fault
I forgot to write down your code and look that one itself up I will try to remember to do it Tomorrow.

This is the best I can do for the P codes.
The OEM codes are according to Volvo's software.
