Hi all hope you are well 😆
So I was hoping some kind person would be able to give me some advice. I am a woman, I have tried my best to understand the following codes.
4873 exhaust gas recirculating cooling plausibility
447B Oxygen sensor -around £50
4CAE exhaust gas recirculation controller position sensor signal - (I think this is the loss of power) check leakage of EGR valve /replace sensor
40D4 exhaust gas recirculation actuator position control
4068 air system air to air EGR mass flow plausibility
Looks like this is all related to the exhaust. What are your thoughts 💭
🤔now the engine management light has only just come on but kept going off now it’s back on 😩 however every now and again when I’m driving it looses power for a few seconds.
🫡with your expert knowledge do you think this is a case of all 5 need replacing or could one thing set the others off ie sensors
🫡cost wise what do you think 💭 I’m on a budget
🫡can I clean the EGR with brake cleaner? where is this located? What do you clean it with?
4CAE -related to ECR controller - opens and closes the exhaust valve flap when engine control sends signal. Sometimes mechanical or electrical EGR sensor fails to open or close EGR valve flap.
4873- monitoring EGR cooler bypass valve/code is logged when the temperature gradient falls below limit value 5k -check vacuum supply to EGR
447b air leak or faulty sensor
thanks 🙏 hope you can help 🙏❤️🫡
