Are you using an Innova code reader? I had this when I used one of the Innova 3030 code readers. I called and they said they were QC codes from manufacturing.

At this point you need to test the signal from the MAP to the PCM (powertrain control module), it should vary between about 1 and 4 volts as you throttle the engine up and down quickly, if little or no change then the heated wire in the MAF is burned out and th sensor will have to be replaced, in that case, they sell rebuilt units at a very reasonable cost, try rockauto.com, best prices around period.

P-0102 and P-0113 are mass air flow and intake air temp codes, the P-0136 is an Oxygen sensor code. Before you do anything, check for debris in the Mass Air Flow Sensor, it's small black box with electrical wiring connector that is screwed into the intake air tube, between the air box and the intake manifold. Undo the screws, remove the sensor, and, with a flashlight, and look down inside it for debeis, or broken wires inside it. If it's dirty, it could throw a P-0136...Comment back on what you find; hope this helps, and thanks for choosing FixYa!

P0102 - Mass Air Flow (MAF) Circuit Low Input
The MAF sensor circuit is monitored by the PCM for low air flow (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine running the air flow (or voltage) changes below a minimum calibrated limit, the test fails. MAF sensor disconnected
MAF circuit open to PCM
VPWR open to MAF sensor
PWR GND open to MAF sensor
MAF RTN circuit open to PCM
MAF circuit shorted to GND
Intake air leak (near MAF sensor)
A closed throttle indication [throttle position (TP) sensor system]
Damaged MAF sensor
A MAF V PID (MAF PID) reading less than 0.23 volts (Refer to equivalent grams/second chart in GO to Pinpoint Test DC ) in continuous memory or key ON and engine running indicates a hard fault.
P0113 - Intake Air Temperature (IAT) Circuit High Input Indicates the sensor signal is greater than Self-Test maximum. The IAT sensor maximum is 4.6 volts or -50°C (-58°F). Open circuit in harness
Sensor signal short to power
Improper harness connection
IAT V PID reading greater than 4.6 volts with key ON and engine OFF or during any engine operating mode indicates a hard fault.

Intake Air Temperature Circuit High Input
It looks like it is related to the IAT sensor or circuit.
