Volvo c30 1.6d edc16c34 limp mode off

[bugarcek]

Hello

I need limp mode off here..

I will get mad with this car... Here already changed turbo, maf, map, turbo regulator, all glow plugs... Car goes perfectly until 3krpm and no rev up...

The only fault in the ecu is p0652 (ecm-8420 read with vida)

Is there any possibility to turn off limp mode?

[Ignasvw]

try and report

Mate, you have electrical problem. Check wiring on ECU.

[bugarcek]

Same problem.... Still in limp mode any other variant?

I just checked wiring to sensors and everything seems ok.

unplug egr and test if the fault the same

check engine will glow but i think no limp mode

post result

make logs from boost please

As i see there is problem with +5v to maf sensor from ecu. It could be ecu problem, if you cheked everything

[bugarcek]

But anway still... If ecu is problem, car goes 100% until 3krpm and than it wont rev up... Ok it could be ecu problem, but still I am thinking if removed limp mode should fix the problem

Will fix your problem not car problem, not good for your customer.

I know, but than we should never do egr off, dpf off or tva off... I know MAF is more important than egr but... It is just funny because car goes 100% ok and wont rev after 3k rpm... the worst was, because somenone before me done dpf off here and erase all dtc, now I load ori file and get this dtc with voltage problem

[morgano]

Put the sw that came with the ecu dpf off and whole dtcs erased and see if car goes well and fault disappear again.

[bugarcek]

I tried now... car not go... And fault is ecm-8420

I also tried to disconnect sensors: camshaft, egr, fuel temp sensor coolant temp, flaps, maf, map... And still error for voltage.... Ecu harness to maf and map also ok

[bugarcek]

Can someone make me dpf and egr off ?

Try this if you want, but i think hide problem is not the way.

good luck.

Thank you Morgano

Now car goes for 10-15 second.... Than again rev limit 3krpm and this faults: B1150, B1120

[bugarcek]

With Morgano file I have been able to find the real problem...

Problem is in throttle actutator... I again tried to load original file and disconnect 1 throttle and dissapered error for voltage reference... But with disconnected throtlle car is again in limp miode...

Faults are: P0488, P0407, P2141...

Hi.

Here, same pass.

Hi. I have the exact same problem with a Volvo V50 1.6 Diesel engine with EDC16CP34 ECU. Can you please help me with the solution that worked for you? Thank you
