P0117 Engine coolant temp sensor low voltage P0102 Mass air flow sensor low voltage Mass air flow sensor is preventing your car from running. Before replacing sensor you should check out the wiring. Both the ECT sensor and MAF sensor share reference voltage and ground wires. Having codes for both sensors makes me believe it is wiring issue. If wires were stripped bare and show any corrosion they should be repaired or replaced not just taped up. These wires are low voltage 5V and any extra resistance will affect sensor operation.
