What does the p0339 code on the crankshaft sensor mean?
The RPM will also be displayed on your dashboard by the crankshaft sensor. The most common symptoms of the P0339 code are no start condition, check engine light, sudden engine stall, and performance issues. The most common reason when it comes to the P0339 code is a faulty crankshaft sensor.
What is the trouble code for the crankshaft?
Trouble code P0339 is triggered when the engine control unit receives an intermittent high signal (voltage) or an error signal from the crankshaft sensor ‘A.’ The function of the crankshaft sensor is to read where the crankshaft is in the cycle. It is used to know when the injectors and ignition coils need to be ignited.
What causes DTC p0339 on a Mustang GT?
If the reluctor ring is rubbing the sensor, the signal will be distorted. Ford Trucks / Mustang GT – An alternator phase problem, such as a blown diode or open coil, may cause so much electrical interference it distorts the CKP signal, causing DTC P0339, in spite of there being no actual problem with the CKP sensor or wiring.
What does DTC p0339 stand for on an ECU?
If the ECU only sometimes detects a CKP signal, it will set a diagnostic trouble code (DTC), DTC P0339 – Crankshaft Position Sensor Circuit Intermittent, and illuminate the MIL or CEL (malfunction indicator lamp or check engine light).
What is the p0339 crankshaft position sensor B code?
If crankshaft position sensor input voltage is too low over a set period of time, a P0339 code will be stored and a MIL may be illuminated. Other crankshaft position sensor B trouble codes include P0335, P0336, P0337, and P0338. Code Severity & Symptoms. A no-start condition will likely accompany a stored code P0339.
What causes a DTC p0339 to not work?
Depending on year, make, and model, DTC P0339 may have number of causes, pretty much the same as those causing DTCs P0335, P0340 or P0345: Faulty Sensor – If the sensor is open or shorted, due to age, damage, or corrosion, a weak signal or no signal will be generated.
When does a p0339 CKP sensor circuit intermittent interruption set?
They were fighting a reoccurring P0339 that would set once on average once per day. A P0339 – Crankshaft Position (CKP) Sensor Circuit Intermittent Interruption sets when the Hall Effect sensor signal received by the PCM has an incorrect amount of signal pulses between reference pulses.
What should I do if my p0339 is reset?
If the P0339 is reset, locate a system wiring diagram from your vehicle information source and check for voltage at the CKP sensor. A five-volt reference is normally used for CKP sensor operation but check manufacturer’s specifications for the vehicle in question. One or more output circuits and a ground signal will also be present.
