1997 Plymouth Prowler V6-3.5L VIN FSECTION P1496 5 Volt Supply Output Too Low
NAME OF CODE
5-Volt Supply Output Too Low
WHEN MONITORED
With the ignition on.
SET CONDITION
The 5-volt supply to the sensors is below 3.5 volts for 4 seconds.
THEORY OF OPERATION
The powertrain control module maintains a 5-volt supply to the MAP sensor, TP sensor, EGR valve, and A/C pressure sensor. It is critical that the 5-volt supply stays between 4.8 volts and 5.1 volts as this input has a direct effect on the sensors output voltages.
POSSIBLE CAUSES
- Shorted 5-volt supply
- Shorted sensor
- PCM failure

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
