TEST
1 NOTE: If the P0107 - MAP Sensor Voltage Too Low is also set, diagnose it
first before continuing with P1296 - No 5-volts To MAP Sensor.
Ignition on, engine not running.
With the DRBIII , read DTCs and record the related Freeze Frame data.
With the DRBIII in Sensors, read the MAP Sensor voltage.
Is the voltage below 2.35 volts?
Yes → Go To 2
No
2 Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Ignition on, engine not running.
Measure the voltage on the (K7) 5-volt Supply circuit at the MAP Sensor harness
connector.
Is the voltage above 4.5 volts?
Yes → Go To 3
No
3 With the DRBIII in Sensors, read the MAP Sensor voltage with the Sensor harness
connector disconnected.
Is the voltage above 4.5 volts?
Yes → Replace the MAP Sensor.
No
