The commonality between all the codes described is a low voltage condition messing with the sensors. To begin with, how's the state of the battery? Any work done to the car recently?
P0107 - BARO/MAP Sensor Low Voltage Detected
Sensor operating voltage is less than 0.25 volts (VREF), as a result it fell below the minimum allowable calibrated parameter.
Open in the circuit, or short to ground
VREF circuit open, or short to ground
Damaged BARO/MAP sensor
VREF should be greater than 4.0 volts
PID reading is in frequency/volts
P0122 - Throttle Position (TP) Circuit Low Input
The TP sensor circuit is monitored by the PCM for a low TP rotation angle (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine OFF or key ON engine running the TP rotation angle (or voltage) changes below a minimum calibrated limit, the test fails.
TP sensor not seated properly
TP circuit open to PCM
VREF open to TP sensor
TP circuit short to GND
Damaged TP sensor
A TP PID (TP V PID) reading less than 3.42% (0.17 volt) in key ON engine OFF, continuous memory or key ON engine running indicates a hard fault.
P0190 - Fuel Rail Pressure Sensor Circuit Malfunction (FRP)
The comprehensive component monitor (CCM) monitors the FRP sensor to the PCM for VREF voltage. The test fails when the VREF voltage from the PCM drops to a voltage less than a minimum calibrated value.
VREF open in harness.
VREF open in sensor.
VREF open in PCM.
Verify VREF voltage between 4.0 and 6.0V.
P0452 - FTP Sensor Circuit Low Voltage Detected
The PCM monitors the EVAP control system FTP sensor input signal to the PCM. The test fails when the signal average drops below a minimum allowable calibrated parameter.
Contamination internal to FTP sensor connector
FTP circuit shorted to GND or SIG RTN
Damaged FTP sensor
FTP V PID reading less than 0.22 volt with key ON and engine OFF or during any engine operating mode indicates a hard fault.
