Todays video we're diagnosing p026a 12642 charge air cooler efficiency below threshold code on my sisters 2013 nms vw passat tdi ckra. started out wit. Speculation: oil water condensation froth creeps into the sensor and decreases resistance, and causes iat portion of sensor to read “implausible signal”. this in turn causes the p026a code as the computer suspects the intercooler is compromised. note: 03g 906 051e = 0 281 002 977 = 0 281 002 976.
2012 passat tdi, ckra engine w dsg transmission cust states engine would start and run fine, but put into gear and engine would bog down and die. difficult to free rev engine, 2500 to 3000 rpms tops. p026a 000618 charge air cooler: efficiency below threshold p0101 000257 mass air flow sensor (g70): implausible signal. Fixing the p026a on an nms passat tdi can be quite the challenge. the code p026a means the charge air cooler efficiency is below threshold, pointing towards the map sensor failing. when removing the map sensor from the car you will most likely find the sensor coated in oil which is triggering the code. a…. Step by step procedure. step 1: scan for dtcs. start by using a diagnostic scan tool to retrieve the p026a and any accompanying codes. note down the dtcs for reference during the repair process. step 2: check and top off the coolant level. inspect the coolant level in the charge air cooler. if low, add the appropriate coolant and check for leaks. 2012 passat tdi se summary: engine cel, ran ross vcds scan, discovered code p026a and p0111. cleared. did research. ordered map sensor (g31). engine cel again. ran ross vcds scan. got same codes. cleared codes. pulled sensor. discovered greenish oil water condensation froth. cleaned sensor, and.

To diagnose the p026a volkswagen code, it typically requires 1.0 hour of labor. the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. most auto repair shops commonly charge between $80 and $150 per hour; however, rates in metropolitan areas or at. Replied by rory67 on topic 2014 vw passat 2.0l tdi crank no start. always check battery in amp clamp i'm going to put a piece of tape and write that on my amp clamp. ecu has injector control, on power and ground side (currant limited 50 volt system). checked timing last night pinned cam pump and crank all good.
