What is the reason for excessive chain noise in timing case?
Timing chain noise is commonly most noticeable during cold startup of the vehicle when oil pressure and oil flow is at its lowest. Excess slack in the timing chain can cause a rattling sound or even a clanking sound if the slack is severe enough to cause the chain to contact the timing chain cover.
When does the p0339 trouble code come on?
The P0339 trouble code is triggered when the engine control unit gets an intermittent high signal (Voltage)/Faulty signal from the crankshaft sensor ‘A’. The crankshaft sensor’s job is to read where in the cycle the crankshaft is.
Why is the p0335 crankshaft sensor no signal?
Honda has determined that the P0335 — Crankshaft sensor no signal and P0339 — crankshaft sensor circuit intermittent interruption trouble codes are caused by corrosion in an electrical connector. Do NOT automatically replace the crankshaft sensor.
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 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).
The P0339 trouble code is triggered when the engine control unit gets an intermittent high signal (Voltage)/Faulty signal from the crankshaft sensor ‘A’. The crankshaft sensor’s job is to read where in the cycle the crankshaft is.
How is the p0339 sensor used in an ECM?
P0339 Description. This information is used by the Electronic Control Module ( ECM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change.
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 causes DTC p0339 to have no CKP signal?
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. Poor Installation – A good CKP signal is highly dependent on sensor placement.
