my 06 ion coupe was throwing P0120, P0123 and P2135 when it rained/snowed. The ECM has 2 large connectors on it. When facing the car the connector on the left had 3 chafed wires right where the wires meet the connector. You will need to remove the connector to see them. I used vulcanizing rubber tape to re- seal and pad them against the connector.
