Yes, I get 0107, 0108, 0205, 1478, 0123, 0118. Last night I was only getting 0107 and 0108 so I replaced the MAP sensor. Now this morning I get the other 4 codes.

All indicate to a short circuit
DTC P0107: MAP SENSOR VOLTAGE TOO LOW
NOTE:For component location.

Manifold Absolute Pressure (MAP) sensor circuit is monitored with engine speed at 600-3500 RPM, Throttle Position (TP) sensor voltage less than 1.2 volts and battery voltage greater than 10.4 volts. DTC will set if Powertrain Control Module (PCM) senses MAP sensor voltage is less than 0.0392 volt for 1.7 seconds.
Possible Causes
MAP Sensor Voltage Below 0.04 Volt
(F855) 5-Volt Supply Circuit Shorted To Ground
(F855) 5-Volt Supply Circuit Open
MAP Sensor Internal Failure
(K1) MAP Sensor Signal Circuit Shorted To Ground
(K1) MAP Sensor Signal Circuit Shorted To (K900) Sensor Ground Circuit
PCM

DTC P0108: MAP SENSOR VOLTAGE TOO HIGH
Monitored & Set Conditions
Manifold Absolute Pressure (MAP) sensor circuit is monitored with engine speed at 600-3500 RPM, Throttle Position (TP) sensor voltage less than 1.2 volts for greater that 1.7 seconds and battery voltage greater than 10.4 volts. DTC will set when MAP sensor voltage is greater than 4.96 volts.
Possible Causes
MAP Sensor Voltage Above 4.6 Volts
(K1) MAP Sensor Signal Circuit Shorted To (F855) 5-Volt Supply Circuit
(K1) MAP Sensor Signal Circuit Shorted To Battery Voltage
(K1) MAP Sensor Signal Circuit Open
(K900) Sensor Ground Circuit Open
MAP Sensor Internal Failure
PCM

DTC P0118: ECT SENSOR VOLTAGE TOO HIGH
Monitored & Set Conditions
Engine Coolant Temperature (ECT) sensor circuit is monitored with ignition on and battery voltage greater than 10.4 volts. DTC will set if ECT sensor voltage at the Powertrain Control Module (PCM) is greater than 4.96 volts for greater than 2.6 seconds.
Possible Causes
ECT Sensor Voltage Above 4.6 Volts
ECT Sensor Internal Failure
(K2) ECT Sensor Signal Circuit Shorted To Battery Voltage
(K2) ECT Sensor Signal Circuit Open
(K900) Sensor Ground Circuit Open
PCM

P0205: INJECTOR #5 CONTROL CIRCUIT

DTC P1478: BATTERY TEMP SENSOR VOLTS OUT OF LIMIT
Monitored & Set Conditions
Battery temp is monitored with ignition on. DTC will set if the battery temperature sensor, internal to the PCM, goes above 4.9 volts or below 0.1 volt for more than 3.2 seconds.

Would the computer be bad, or is it just a short in a common wire somewhere?

Have to check wiring system and harness 1st use an OHM meter and check wiring back to the PCM if all checked OK suspect bad PCM
