This morning commute the FieSTa popped up the icon we all love to hate. This will mark the first time in my entire vehicle ownership history where a MIL has occurred without me immediately/already knowing what it’s about.

The scantool is at home, I might pop home on lunch just to have a peek at what the codes say. (~34,000 miles no noticeable running issues, fuel economy as expected, etc. etc.)

That means it is ready for helicopter mode.

40,000 in mine and the only time it threw a code at me was because I was teaching the girl how to drive manual and she stalled it three times so it lit up the “maintenance needed” wrench icon.....Or it was calling her a spanner. It is pretty british....

My check engine light has been on for over 3 years and 70k miles.

I got the Spanner once, first week I owned the car... missed a hard shift from 3-4, went 3-2 instead... reved it right up to about 8000. No harm, no foul, just pissed off the computer ;) (I quickly learned to trust the transmission and that I didn’t need to be forcing it into gears, never had that happen again)

HEMIWagon finally threw a CEL last night. Felt like it was cutting power and refusing the shift getting anywhere near WOT, turns out the Cam Position Sensor is on the fritz. Should be replaced tonight and ready to terrorize the streets again.

I don’t know if that’s a good idea. Remember what happened last time?

Haha do you have that saved?!

But really, if Mercedes wants to install an engine pre-heater thats cool. Just dont expect me to replace a heater for something that literally runs on explosions.

Nah, GIS your name and SC400 and it’s like the first result. I just haven’t taken the piss out of you in months. Figured it was overdue.

Coolant bypass valve.

Edit: Change my mind

Cannister purge valve, check to see if the fuel tank has actually collapsed as well. TSB is to replace the cannister purge valve, fuel tank, fuel pump, & charcoal cannister.

haha, actual code is Poo7B, Charge-cooler temperature sensor range/function (high). This indicates that the charge temperature sensor idicated a temperature ABOVE the measurable range (250 degrees C(?)). It’s most likely the sensor or the harness as everything seems to be running as expected and fuel economy has not changed from expected. (interittant failure?)

Actual code: P007B; Charge-cooler temperature sensor function/range (high). The sensor indicated a temperature above the measurable range. Probably bad sensor, or wireing issue, as anything regularly heating the air coming out of the intercooler to that point should be effecting performance/running.

P007B - Charge Air Cooler Temperature Sensor Circuit Range/Performance (Bank 1)

!!! UNKNOWN CONTENT TYPE !!!

This pinpoint test is intended to diagnose the following:

intake air temperature (IAT) sensor (12A697)

turbocharger boost pressure (TCBP) sensor (9F479)

turbocharger boost pressure (TCBP)/charge air cooler temperature (CACT) sensor (9F479)

manifold absolute pressure (MAP)/ charge air cooler temperature (CACT) sensor (9F479)

manifold absolute pressure (MAP)/intake air temperature 2 (IAT2) sensor (9F479)

powertrain control module (PCM) (12A650)

!!! UNKNOWN CONTENT TYPE !!!

Note: Diagnose and repair all circuit DTCs before diagnosing range or performance DTCs.

Are DTCs P007B, P0096, P0106, P0111, P0236, or P00CE present?

!!! UNKNOWN CONTENT TYPE !!!

Are DTCs P007B, P0096, P0111 or P00CE present along with other DTCs?

!!! UNKNOWN CONTENT TYPE !!!

Cold soak the vehicle at ambient temperature for at least 6 hours.

Ignition ON, engine OFF.

Access the PCM and monitor the CAC_T (TEMP), IAT (TEMP) and IAT2 (TEMP) PIDs.

Are the IAT, CACT and IAT2 temperature readings within 16.67°C (30°F) of each other?

!!! UNKNOWN CONTENT TYPE !!!

Allow the engine to idle at the normal operating temperature.

Access the PCM and monitor the CAC_T (TEMP), IAT (TEMP) and IAT2 (TEMP) PIDs.

Drive the vehicle at a steady speed of 88 km/h (55 mph) for a minimum of 6 minutes.

Does the IAT temperature exceed 65.5°C (150°F), or does the CACT temperature exceed 104.4°C (220°F), or does the IAT2 temperature exceed 115.6°C (240°F)?

!!! UNKNOWN CONTENT TYPE !!!

Are DTCs P0106 or P0236 present along with other DTCs?

!!! UNKNOWN CONTENT TYPE !!!

Note: All PIDs may not be available on all vehicles.

Ignition ON, engine OFF.

Access the PCM and monitor the BARO (PRESS), MAP (PRESS) and TCBP (PRESS) PIDs.

Is the suspect sensor PID reading within 10.35 kpa (1.5 psi) of the other sensors?

!!! UNKNOWN CONTENT TYPE !!!

Remove the MAP/CACT, MAP/IAT2, TCBP, or TCBP/CACT sensor. Refer to the Workshop Manual Section 303-14, Electronic Engine Controls.

Carry out a visual inspection.

Check the sensor port and inlet for:

contaminationrestrictionscarbon build-up or deposits

Is a concern present?

!!! UNKNOWN CONTENT TYPE !!!

Disconnect all the PCM connectors.

Visually inspect for:

pushed out pinscorrosion

Connect all the PCM connectors and make sure they seat correctly.

Carry out the PCM self-test.

Verify the concern is still present.

Is the concern still present?

And that’s as far into the rabbit hole I can go at the moment.
