    Hello

    After remove the air filler and rest of part to vacuum up the oil down of throttle body approx 2 teaspoon every 3-4months and everything are place back in normal. A check engine light ON and Torque scanned with P0113 & P0102 code.

    So, I disconnect and reconnect the Mass flow senor and check everything are connected correctly. Clear the fault on ECU and Check Engine light off and running fine. Every time I run the Torque scan code again the code P0113 and P0102, but NO Check Engine light. Please advise. thanks

    P0113 (Intake Air Temperature circuit hight input
    P0102 (Mass or Volume Air flow cicuit low input

    Oil down of throttle body even with Oil catch installed excessive oil down in the throttle body with acceleration.

    Shooting from the hip: if the MIL (aka Check Engine Light) isn't coming on, these are not current codes then right?. (Or so intermittent that they aren't ever happening twice in row, since it's a 2-trip detection for at least the P0102.)

    I forget at the moment how it looks on Torque but you can tell the difference between current, pending, and "permanent" codes. They ought to self-clear after enough trips that meet the confirmation conditions. The repair manual will have deets on what those confirmation conditions are.

    Can confirm. I forgot to plug in the MAF after some maintenance…got the same codes and they stuck around even after the CEL went off. Don’t know if it’s mileage driven or a certain number of on/off cycles, but the codes went away after a day.

    Facing the same issue here right now. Have you solved the issue, Tekken?

    Those two codes (both resulting from having that sensor unplugged) stick around as 'permanent' codes until the car actually sees the necessary driving conditions to confirm they've been fixed. I had a permanent P0102 for a year because my COVID lockdown driving never met the conditions to clear it. Finally got rid of it once Elektroingenieur kindly looked up the right confirmation driving pattern for it.

    Got rid of the code by disconnecting the MAF, blowing the sensor & connector with compressed air, and re-connecting it back.

    Jenny, did you have a check-engine light before?
