Another thread regarding the " P026A 00 [237] - Efficiency Below Threshold" code
Yup, like it says.
EDIT:
model year corrected
The car is a 2014 Passat and it is getting the below code:
12642 - Charge Air Cooler
P026A 00 [237] - Efficiency Below Threshold
MIL ON - Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Status: 00000001
Fault Priority: 2
Fault Frequency: 1
Mileage: 141822 km
Date: 2031.14.31
Time: 13:39:33
Engine speed: 1535.00 /min
Normed load value: 51.8 %
Vehicle speed: 81 km/h
Coolant temperature: 77 °C
Intake air temperature: 63 °C
Ambient air pressure: 990 mbar
Voltage terminal 30: 14.260 V
Unlearning counter according OBD: 40
Air mass at air mass meter 1: 99.0 kg/h
Temp sensor for low-pressure EGR after cooler: raw value: 67.5 °C
Outside air temperature: 1.5 °C
Intake air temperature before throttle valve: calculated: 27.2 K
Sensor for temp after charge air cooler: raw value: 63.7 °C
Coolant pump for charge-air cooling: spec. value: 95.00 %
============
From what I have read in all the threads, it seems like the cause was due to having a winter front installed and that prevented air flow from creating enough difference between the in and out of the intercooler.
There is no winter cover on this car. So what gives?
Could it be the intercooler's coolant pump? Looks like it is at 95%
Does that mean it is almost full on?
What kind of measurement is the 27.2K ?
i.e.,
Intake air temperature before throttle valve: calculated: 27.2 K
Yup, like it says.
