Do This, If You Replaced Crankshaft Position Sensor But Still Get Code?

If you have replaced the crankshaft position sensor but still get the same code, you could do a few things to clear that up. Find all that is explained in this post.

First things first, check all of your connections and make sure that they are intact. They may also need replacing if any of them appear loose or damaged.

The second step would involve using an OBD-II scanner tool to read any additional codes stored in your car’s computer system, which could provide more information about what might be causing this issue with the crankshaft position sensor code being thrown up on your dashboard display panel warning light indicator.

This will help narrow down potential causes so you can focus on fixing those specific issues instead of having multiple possibilities all at once without knowing exactly where each one begins and ends within the system itself. And to do this I will address the problem with a replaced crankshaft position sensor but still get code as follows:

First I will begin with a few of the common problems after replacing crankshaft position sensor, what to do, replaced camshaft position sensor but still get code, the overview of the p0335 crankshaft position sensor a circuit malfunction, then move on to how to fix crankshaft position sensor a circuit malfunction and next is the fix for bad crankshaft position sensor no code

and finally what to do if your car won’t start after replacing crankshaft position sensor. So with those in mind lets get right to them.. 

Common problems after replacing crankshaft position sensor

After replacing a crankshaft position sensor, one common problem is incorrect readings from the new one being sent back to the computer system. This can cause misfires due to incorrect spark timing or poor fuel economy because of inaccurate air/fuel ratios being used by your car’s ECU (Engine Control Unit).

Furthermore, if not properly connected during installation, you could experience stalling or hesitation while driving, which could lead to further damage if left untreated for too long.

What to do when you replace camshaft position sensor but still get code

If the camshaft position and codes are still present after replacing the sensor, make sure that the new sensor was installed correctly and is functioning properly.

Something that can cause an error code even after replacing the camshaft position sensor is an issue with one or more of its related components, such as wiring harnesses, connectors, or relays. It’s important to inspect these components for any signs of damage or corrosion that could be causing problems with communication between them and the computer system in your vehicle.

Additionally, if any parts were damaged during installation, they should also be checked for proper functionality before continuing further diagnostic efforts on this problem.

P0335 crankshaft position sensor a circuit malfunction

The P0335 Crankshaft Position Sensor (CPS) monitors the position and rotational speed of the crankshaft, which allows for proper ignition timing and fuel injection control.

A malfunctioning CPS can cause significant problems with your car’s performance, including rough idling, stalling, or misfiring. To diagnose this issue correctly, it is important to understand what causes a circuit malfunction in the first place.

A circuit malfunction occurs when there are issues within the electrical wiring that connects components on your vehicle’s engine. This could be caused by several things, such as corrosion due to moisture buildup or damage from physical contact with other parts of your car’s engine bay area like belts or hoses rubbing against them.

Over time, wear and tear on the insulation material covering wires, making them exposed. Short circuits are created between two points that should not be connected, otherwise known as “crossed wires.”

How to fix a crankshaft position sensor circuit malfunction

The first step in fixing a crankshaft position sensor circuit malfunction is to check for any loose connections or damaged wiring that might be causing the issue.

Make sure all wires are securely connected and replace any frayed or broken ones if necessary.

If no broken wires were found, then the next thing you need to do is inspect all connectors attached directly to the backside of the crankshaft sensor housing, making sure none of them have become corroded over time due to wear and tear exposure to the elements.

If corrosion was detected, then clean out the affected area using an appropriate cleaning solution before reattaching connectors securely and firmly so the problem won’t recur anytime soon.

Once these checks have been completed successfully, try starting up your vehicle once more; if you still experience issues, then proceed with further troubleshooting methods such as the testing voltage at various points throughout the system using an ohmmeter or voltmeter device.

In some cases where other methods fail, it may be necessary to replace either part of or even the entire crankshaft positioning system, depending on how extensive the damage may have been.

Fix for a bad crankshaft position sensor with no code

A bad crankshaft position sensor can be a difficult problem to diagnose, as it usually does not produce any codes that could point to the issue. However, there are some steps one can take to fix this issue and get their vehicle running properly again.

bad crankshaft position sensor no code

Check if the sensor itself is actually faulty or if it’s just a wiring or connection problem. To do this, you need to use an ohmmeter and measure resistance across the terminals of the connector for your crankshaft position sensor.

All good sensors should have around 500 ohms of resistance when measured in this manner. If your reading is zero, you know something is wrong with your wiring or connections somewhere along the path from the battery power source down into the engine bay area where the CPS is located – so check those before proceeding.

If, after checking everything, you still have no luck getting readings from the CPS, then chances are high that the actual unit itself needs replacing, which isn’t too difficult as most vehicles make them easy enough to access and replace (remember to disconnect the battery ground cable before doing work).

After installing the new part, reconnect the cables securely, making sure they’re tight-fitting onto terminal posts on both ends, before testing the system again using the same method as before.

Measuring the voltage across terminals while turning the ignition switch “on” (not “start”) should yield correct readings, indicating a successful replacement job done correctly!

What to do if the car won’t start after replacing the crankshaft position sensor

Have you checked all the connections related to the crankshaft position sensor? Make sure that they are securely connected and that there isn’t any corrosion on them or other signs of damage.

If everything appears normal, you should check other components such as spark plugs, fuel injectors, ignition coils, and wiring harnesses for any signs of damage or wear-and-tear that could cause an issue with starting your vehicle again after replacing the crankshaft position sensor.

Finally, suppose you have ruled out all possible issues with these components. In that case, you may want to consider taking your car to a mechanic for further diagnosis and repair work, as more complex problems may require professional attention.


When dealing with persistent error codes even after replacing the crankshaft position sensor, you should thoroughly inspect all associated components to diagnose and solve whatever underlying problem.
