Can camshaft sensor cause no start?
If you ignore the symptoms listed here and your camshaft position sensor fails, your vehicle will not start. As a camshaft position sensor weakens, so does the data it transmits to the ECM. Eventually the data signal becomes so weak the ECM switches off fuel and spark delivery, and your engine will not start.
Can crankshaft sensor cause no start?
A bad Crankshaft Position sensor is a common cause of no starts. The signal from this sensor goes to the PCM or ignition module that switches the ignition coil(s) on and off. The voltage should be switching on and off.
What is code P0338?
P0338 is a diagnostic trouble code (DTC) for “Crankshaft Position Sensor A Circuit High Input”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What happens if a crank sensor goes bad?
If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall. This is usually a symptom of a wiring problem, however a bad crankshaft position sensor can also produce this symptom.
How do I fix code p1345?
Loose the distributor hold down bolt with engine OFF. Make sure your OBD scanner is plugged in to monitor the Cam Retard Offset reading. Turn the engine on, let it warm to normal operating temps, and get the rpm’s above 1,000. If your reading is negative, turn the distributor counterclockwise.
What is P0328 code?
The P0328 code is telling us that there is a high input from the bank 1 knock sensor 1. The ECU detects excessively high voltage that is out of range of the knock sensor. This leads to the Check Engine Light being displayed on the dashboard.
How can you tell if the crankshaft position sensor is bad?
Symptoms of a Bad Crankshaft Position Sensor
- Your Check Engine Light is Blinking.
- It’s Difficult to Get Your Vehicle to Start.
- Your Vehicle is Stalling and/or Backfiring.
- The Engine is Making Your Vehicle Vibrate.
Can I drive with a bad crankshaft sensor?
Once the position sensor becomes compromised or if you have symptoms of a problematic crankshaft that you can’t ignore, do not drive your vehicle. If the problems are more severe, driving can cause substantial engine damage that could cost you a lot more to repair.
Can a p0338 be stored in a no start condition?
When a P0338 is stored, a no-start condition will likely accompany it. For that reason, this code should be categorized as severe. If the engine will start and run, there remains a high risk of a no-start condition in the near future. Symptoms of this code may include:
What is the p0338 code for the crankshaft position sensor?
The PCM constantly compares input signals from the crankshaft position and camshaft position sensor circuits. If CKP input voltage is too high over a set period of time, a P0338 code will be stored and a MIL may be illuminated. Other crankshaft position sensor trouble codes include P0335, P0336, P0337, and P0339.
Can a post Cat O2 sensor be replaced?
I replaced post cat O2 sensor to new Denso O2 sensor. But the same lights and code came back soon. Below are the recorded graphs while I was driving with new O2 sensor. AFR looks okay. Still O2 sensor output voltage stuck to 0.9V. It went low boltage only when I released the accel pedal in decending slope.
