P1340 Fault Code: Crankshaft and Camshaft Position Sensor Indicates Out of Sequence.

If you notice that your Check Engine Light (CEL) is on, the very first thing you need to do is purchase an OBD-II scanner so that you can figure out what is making the light come on. The scanner will display one of two messages if a P1340 code appears: “Crankshaft/Camshaft Position Sensor Readings Out of Sequence” or “Camshaft Position Sensor (G40) + Engine Speed Sensor (G28): Incor. Correlation”. However, you shouldn’t worry since it really sounds better than it is. In the best case scenario, a malfunctioning crankshaft position sensor or camshaft position sensor is to blame and has to be replaced when this code appears. In the worst situation, your engine’s timing is incorrect, which may lead to expensive repairs if not addressed. The presence of this error number usually indicates improper installation of the timing belt or chain.

I have a P1340 error code on my Volkswagen or Audi; am I safe to drive?

You may drive on it for a brief length of time if your engine isn’t performing poorly, however it is not advised. When an engine’s timing is incorrect, it may lead to a number of serious problems, including knocking, lower fuel economy, overheating, and poor performance. Complete engine damage is likely if you disregard this warning. Get it to a repair shop right away, or at least investigate the potential problems we’ve outlined below.

Symptoms of a P1340 Volkswagen or Audi:

• Having the check engine light on
• Slow Start-Up Delay at Low RPMs
• The engine either won’t start or won’t start right away.
• Engine stalls at a Rough Idle
• Misfire in the engine

Possible Causes of Engine Error P1340 in Volkswagen and Audi Vehicles

• Failure of the camshaft position sensor
• Crankshaft position sensor failure.
• Incorrect installation of the timing chain or belt.
• As the timing chain loosened,
• Mistiming the engine
• Malfunctioning engine speed sensor

Fixing a P1340 Engine Error on an Audi or VW

Since the Volkswagen/Audi 1.8t engine appears to be the most common engine with this code, we want to make it clear before we get into the recommendations that they are all for that engine. Feel free to post in the comments if you need help finding components or instructions for a car that isn’t a 1.8t. Check the compatibility of your vehicle with the following replacement components. Because, as was just said, the engine code seems more serious than it really is, let’s get right down to figuring out what’s wrong and fixing it.

How to Change a Camshaft Position Sensor?

Two typical ways to resolve P1340 Volkswagen and Audi fault codes are described below. The speed and location of the camshaft are constantly tracked by a sensor. Poor shifting, worse fuel efficiency, abnormal air-fuel ratios (AFRs), and a nonstarting engine are all possible results of a faulty camshaft sensor.

Crankshaft Position Sensor Replacement Instructions

Crankshaft, valve, and piston status may all be tracked with the use of a sensor that measures rotational speed. If the crankshaft position sensor fails, the engine may stall, vibrate excessively, or refuse to start altogether.

What to Do When Your Timing Belt Breaks

A timing belt that is too tight or has stretched too thin is another typical cause of this engine code. Together, the crankshaft, camshafts, and cylinder head are driven by the timing belt. Should it fail, the engine’s inner workings might be severely damaged. Even though it’s not the simplest do-it-yourself project, we recommend changing the tensioners, water pump, and belt to guarantee that all of the components are brand new and error free.

Conclusion for the P1340 VW Fault Code

The P1340 code in your Vw or Audi should be gone now that you’ve tried the solutions mentioned. As before, this code is not entirely off-limits for driving, although it is strongly discouraged. An issue with the timing belt or chain, or the position sensor for the camshaft or crankshaft, is usually the culprit. Feel free to get in touch with us in the comments if you’re trying to adapt this code to work with another engine, and we’ll do our best to help.
