Error Code P0347: What It Means & What To Do?

<<See All OBD Codes

Is your Car’s Check Engine Light illuminating on the dashboard? Do you find sudden decrease in the fuel economy? And is the car engine running rough? This might be the indication of problems with the Can Position Sensor of the car which in other words can be an OBD P0347 error.

The camshaft position sensor reacts to a toothed wheel on the camshaft, which gives the ECU constant information on its speed and position. If the ECU detects a low resistance (short circuit), it will set DTC P0347 – Camshaft Position Sensor Low Input. Engines like V6 or V8 have two banks, Bank 1 and Bank 2, and would therefore have two CMPs, so DTC P0347 would refer to Bank 2. Sensor A indicates that the malfunction is occurring with the camshaft position sensor circuit that pertains to the intake camshaft.

What causes this problem with the Camshaft Position Sensor A Circuit Low Input (Bank 2)?

• Faulty starter motor
• Faulty camshaft/crankshaft position sensor
• Shorted or open sensor harness
• Bad electrical connections
• Bad battery and car cables
• Bad Wiring to the starter

1. Camshaft Sensor - The main indicative of OBD Code P0347 is a faulty exhaust camshaft. Immediate replacement is required. Visit us today to get all camshaft related replacement parts.
2. Powertrain Control Module - Any fault with the Powertrain Control Module can also cause the P0347 code to the flashed. Get it checked and replace if needed. Buy new components form us.
3. Diagnostic Tool - Always use a professional factory grade OBD scanning and testing tools to diagnose the OBD errors. Buy quality tools from us now!
4. Starter Motor - If the starter motor is damaged, it needs immediate replacement. Buy new motor now!
5. Car Battery & Cables - If the cables related to battery and the battery itself is not working properly, it’s time for replacement. Buy new battery and parts now!
6. Ignition Spark Plug - If the ignition spark plugs have gone bad, it should be replacing immediately. Buy now!
7. Timing Belt and Pulleys - Timing belts and parts are important components and should be replaced if faulty. Buy new timing belts and parts now!

Most common symptoms for OBD code P0347 include a no start condition, extended cranking before engine starts, hesitation upon acceleration, and decreased fuel mileage, along with a stored trouble code and malfunction indicator lamp illumination. Other codes will also likely accompany this type of code including engine misfire codes, lean and/or rich exhaust codes, and mass airflow sensor codes.

Common Symptoms.

• Decreased power and acceleration
• Engine is stalling or hesitation on acceleration
• Engine dies or is difficult to start
• Affected fuel economy

After you know the symptoms of your vehicle’s problem, it becomes easy to detect it and get started with solving it. So, next on our list is few common steps to correct this issue with your vehicle.

• Faulty battery and cable replacement
• Replacement of corroded and damaged wiring and connections
• Starter motor replacement
• Camshaft sensor connector replacement
• Replace the CPS, or camshaft position sensor

Apart from this, you might need to replace other damaged parts too like Position Sensor, Powertrain Control Module, Ignition spark, Battery, Starter Motor. You can easily find all these parts with us. Not only that you can get these parts shipped to your door free, if your cart value happens to exceed $99.

It is very important to use the correct tools to diagnose a problem with a very professional outlook. Each and every default component needs to be examined as the ECM sensor comes into play. Follow the following step by step analysis to do the diagnosis of error code P0347.

• Use a professional grade Diagnostic scan tool to check for all codes present (must be used to show live sensor data).
• Observe and take note of any freeze frame data that is associated with the code along with the current collected data after the test drive.
• After the confirmation of P0347, clear the code and perform a test drive under the same circumstances shown in the freeze frame data.
• If the P0347 code returns, visual inspection is performed to check the integrity of the wiring and camshaft position sensor.
• Check and test the ECM if the sensor checks out as under the rarest of chances it may be possible that ECM is faulty and needs replacement.

Common Mistakes When Diagnosing OBD Code P0347

Never directly assume the Camshaft Sensor is bad and needs replacement. The test procedure must be followed at all times to ensure that the wiring and other components are in good condition. Most of these problems are related to wiring touching the battery or starter motor. Always seek professional help to get the diagnosis as there might be many occasions where the diagnosis is much cheaper than perceived.
