Hello. I scaned my car and got 24% load_pct. Is it normal? Need help. The egr pct 4.7%
And egr_err -24.2%
I have a hyundai 2.5 turbo diesel 140000 km
Thank you
What is the exact fault code & what are your symptoms?
That's not really a fault code.
Anyway, the EGR PERCENT (egr pct) is the "command egr position". This is the percent that the computer is commanding the egr valve to open.
0% being the computer commands the egr valve to Fully Close, 100% being the computer commands the egr valve to Fully Open.
EGR ERROR (egr_err) is a parameter also displayed in a percentage. It uses a formula using the aforementioned (Command) EGR PERCENT and what the EGR Position Sensor is reporting.(The Actual EGR Position)
(if you're interested in the math):
(Actual EGR Position − Commanded EGR) ÷ Commanded EGR = EGR Error.
So for example:
If the EGR valve is commanded open 10% and the EGR valve moves only 5% (5% − 10%) ÷ 10% = −50% error.
So what causes the discrepancy?
You have a diesel, it's likely that you have soot clogging your EGR Valve preventing it from closing all the way, in which case you'd remove and clean your EGR Valve.
OR
You have a faulty EGR Position Sensor in which case you'd replace the sensor.
But you aren't throwing a code so at this point you really don't have to do anything
I saw a leek somewhere under the intercooler so i have to check it out first
Lotus relatively normal but the EGR is somewhat off
What should i do now to find the problem and eventually fix it. Thank you
Waiting for response. Thank you
