2004 Kia Optima P0102 Fault: Car Shuts Off When Accelerating - MAF/VAF Circuit Issue

Model: 2004 Kia Optima Fault Code: P0102 Posted: 2016-03-23 13:48

My 2004 Kia Optima starts and idles normally, but immediately shuts off when the gas pedal is pressed. The diagnostic code displayed is P0102, indicating a problem with the Mass Air Flow (MAF) or Volume Air Flow (VAF) sensor. We have already replaced the MAF/VAF sensor, but the issue persists. Given that the vehicle still shuts down during acceleration, I suspect a circuit-related fault rather than a faulty sensor. What other troubleshooting steps should be taken? Specifically, how can we verify wiring integrity and electrical signals at the MAF sensor for both 2.4L and 2.7L engine variants?

You replaced the part, but P0102 typically points to a circuit issue rather than a faulty sensor. First, inspect the wiring harness at the MAF sensor. For 2.4L or 2.7L engines, check for proper voltage levels including reference voltage, ground connection, and signal (return) voltage to ensure accurate readings and rule out electrical faults.
