CLS 320 cdi....

[Richiemat]

Hi,

Read the codes on the 2006 cls earlier as the EML light was on a few times recently but out again at the moment and found the following(Fault log report generated by Torque for Android):

Current Fault Log

P0111: Intake Air Temperature Circuit Range/Performance Problem
P1111: ?
P0102: Mass or Volume Air Flow Circuit Low Input
P1102: ?
U0101: not too sure
P0100: Mass or Volume Air Flow

Other discovered fault codes

P2510: ECM/PCM Power Relay Sensor Circuit Range/Performance
P2616: Camshaft Position Signal Output Circuit High
P3053: Unknown code - More information may be available on the web
P3052: Unknown code - More information may be available on the web
P2603: Coolant Pump Control Circuit High
P2602: Coolant Pump Control Circuit Low
P2241: 2) O2 Sensor Positive Current Control Circuit Low bank2 Sensor1
P2209: NOx Sensor Heater Sensor Circuit Range/Performance bank1
P2210: NOx Sensor Heater Sensor Circuit Low Input bank1
P2211: NOx Sensor Heater Sensor Circuit High Input bank1
P2627: O2 Sensor Pumping Current Trim Circuit Low bank1 Sensor1
P2601: Coolant Pump Control Circuit Range/Performance
P2600: Coolant Pump Control Circuit/Open

My interpretation is it may need an IAT sensor, not sure how many others are associated to this sensor?

Does anyone else think I am on the right track, any other pointers much appreciated

Many Thanks in advance

I would clear the codes and road test it and see what codes come back.......

 

[Richiemat]

I cleared them and restarted it, they came back

 

[Cole@MBS]

I would say you have a wiring fault then to have all them codes come straight back........

 

[Richiemat]

I'm more confused now

Was hoping it would be a case of replacing sensors one by one and knocking the codes out

Im with Cole on this one, you either have a code reader that isnt deciphering codes properly (which is my guess given that you have unknown codes being produced) or a mass wiring fault.

I would get it on a STAR machine and look at some live data before guessing at and buying various sensors

It never works like that, some codes are related and will come up just because the vehicle went into limp mode.

All of those seem to relate to electrics, but too hard to put together.

Did the codes come from STAR

 

[Richiemat]

Thanks guys, these came from a elm Bluetooth reader and the torque app so it's entirely likely that its at fault especially if the codes don't seem to relate....

 

[television]

Yes that is it,,,seen it before, it does need STAR

 

[Richiemat]

I'm going to check the electrical contacts on each of the sensors to make sure there's nothing untoward, just another thing to try before going near the dealer or changing sensors I guess.

I've found a potential air leak in one of the hose connections, refitted the hose and now have the following codes:

End of report.

Does this make anymore sense to the previous?

Many thanks
