All sensors send data to the ECM, (they do not receive data). When a sensor is disconnected, ie MAP sensor, the ECM applies a substitute value for the sensor based on other sensor inputs. If there is a problem with the MAP sensor, it will set a DTC and illuminate the SES light.
Check voltage at the TPS with the key on, engine off: Gray wire should be approximately 5 volts. Dark blue wire should be less than .25 volts. Turn the ignition off, disconnect the TPS connector. Black wire should be less than 5 ohms to ground in the vehicle harness. Post your results, (don't just replace the TPS).
The P1133 gave you a "set" of DTC's, after you replaced the Oxygen sensor, the P1133 went away. The P0122 has given you a new "set" of DTC's. After it is diagnosed and repaired, clear the DTC's, complete a drive cycle, and continue if the SES light comes on again.
