Renualt Check Injection

[bigbertie]

Hi guys I have replaced engine in scenic 1.6 petrol, now have check injection on dash, had two error codes and replaced throttle position sensor and inlet manifold sensor. Cleared codes still got error message and runs in limp mode. Have replaced throttle body . Diagnostic codes were p0105 p365 . Have also replaced cam sensor. Any ideas to what problem is, as it seems a common fault with Renualts

Forgot to add, does ECU require upgrade or reset

Does any know who can do this for me in Bristol Area?

What Tool did you use to diagnose this fault codes..........

[bigbertie]

Shitty mickey mouse RAC Diagnostic tool. Also mechanic who fitted engine used a snap on tool to reset,but said he couldn't clear fault either

Hello there mate, did the throttle body/manifold come with the replacement engine?
The throttle body usually requires adaption to the car to counter individual tolerances learning full throttle and home position etc I have had to do this on several vehicles that required replacement throttle body. On some vehicles you only have to disconnect this and turn the IGN and it requires setting up again. Annoying I know, they call it progress......what was wrong with a bit of cable and a butterfly?
Can't say for sure on that vehicle, but if you have the old throttle body it might be worth a crack. I recently contacted people on the garageforum asking about Clip services local to me, you might be able to find someone on here or on there.

Thanks for the info, had to replace inlet manifold and throttle body to new engine. What do u mean by "adapt throttle" do I need a ecu reset or something similar. I've seen this check injection fault all over net with no solutions, so anything is worth a try, as I need a return on my investment

Adaption is what the process is called but its just a poncy name for allowing the ecu to recognize a certain components spec. For example and electronic control throttle body will have its own tolerances within potentiometers etc this will almost certainly vary from unit to unit. The ecu has to realise the throttle bodies spec otherwise how does it know where full throttle is etc. As I say cant specifically vouch for this car but I know alot of modern systems require this procedure, on other components as well. As I said earlier, annoyingly some cars lose this information to easily, i recently had a it with a k12 micra that was unable to idle after an engine change. Some diag tools will have the feature of adaption along with reading erasing codes etc. Unfortunately most tools are a jack of all trades, does you mate have a snap on scanner?

[stupidCANt]

Ah just looked those codes up. You don't know about the MIL light status before the engine change??
Most sensors work in a similar fashion... it might be worth checking a few things first :

If your cam sensor has three wires it may have the following connections:

+ 5V
Ground
signal


If your map sensor has three wires:

+ 5V
Ground
signal

The commonality between these two components is that they probably powered from a 5v supply in the ECU.

If you can use a multimeter you can check that 5v and ground are available. The signal wire can only be tested when the sensor is connected. The map sensor will be a voltage that represents the pressure in the inlet, The cam sensor will be a waveform.

Cant say for that car specifically but alot of systems work in similar ways. If your cam sensor only has 2 wires chances are that it will put out an AC waveform.

Worth checking before any more wonga is spent.

What you have said sounds about right! It will not rev the full range. Yes he has snap on tool, will call him to see if it has this feature. Thanks all the info has helped a lot! Will let all know if this has worked

Engine was blown when I bought as it was salvage repair vehicle and totally gone. Info u have given me is totally over ny head

Ha no worries, if it wont rev up the adaption seems a viable option.
Yeah let us know. Interesting fault.

[bigbertie]

Yes mate, if you google "check injection Renault" it seems like a massive issue with them. Will update though as this has been frustrating as hell! Normally use this site for satellite side but you guys have given me some great ideas to try!
