6E2–123 RODEO 6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS about 3-6 g/second at idle to 100 g/second or greater If DTC P0102 cannot be duplicated, the information Test Description Number(s) below refer to the step number(s) on the 2. This step verifies that the problem is present at idle. 4. A voltage reading of less than 4 or over 5 volts at the MAF sensor signal circuit indicates a fault in the 5. This verifies that ignition feed voltage and a good ground are available at the MAF sensor. DTC P0102 – MAF Sensor Circuit Low Frequency
