both codes refer to the throttle position sensor, the sensor is at the throttle plate, on the side of the throttle body. to test remove the connector to sensor, use a ohms meter to test. put 1 lead to top connection and the other to the bottom one. move throttle and the needles on the ohms meter should move very even, move throttle slow to get a good reading, needle should move without no hesitation, if the test is bad replace tps sensor. if the sensor gets to bad, it can have an effect on transmission shifting. after fixing sensor have the light turned of with an obd2 scanner.
