B0721 Chrysler Thunderbolt OBD Code

OBD/2 B0721 error code description and symptoms.

Fuel Rail Pressure Sensor in Range But Low The comprehensive component monitor (CCM) monitors the FRP pressure for acceptable fuel pressure. The test fails when the fuel pressure falls below a calibrated value. Low fuel pressure Damaged FRP sensor Excessive resistance in circuit Low or no fuel A FRP PID value below 551 kpa (80 psi) indicates a failure Low or no fuel A FRP PID value greater than 896 kpa (130 psi) indicates a failure.

Circuit High Input codes like B0721 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

The scent may B0721 signal oil or coolant leaking from their normally closed-loop systems, or it may indicate dangerous exhaust gases invading your car's interior. Car and truck exhaust contains toxic gases such B0721, so if the inside of your car a/c compressor temperature sensor malfunction as if you were standing behind your car, get out and get it fixed. Fight the urge to take a little nap first. So sleepy. That's the carbon monoxide talking, friends. At least open a window on your way to the shop.

Common Causes of Chrysler Thunderbolt B0721 OBD2 Code

A common cause of code B0721 is the failure of A/C Compressor Temperature Sensor Malfunction, but there are several other possible causes as well, such as ;

Erratic camshaft position due to low oil pressure
Faulty Intake Valve Timing Control Solenoid Valve
Faulty Intake Valve Timing Control Solenoid Valve
Faulty front heated oxygen sensor
