Start by inspecting the wiring harness between the firewall and crank sensor for any obvious damage. Enter the 5 character trouble codes in the search box and submit the search. Make sure the silicone sealing ring is in place on the electrical connector before reconnecting. If the air gap is wrong, the engine may not start or will start but run rough. You may break the wires. Conversely, as either a tooth leading or trailing edge aligns with the sensor, the magnetic field disturbance and induced voltage are greatest.
Hi Matt, I think I missed the point you are trying to drive at. Other related crank sensor error codes include P0016, P0017, P0018, P0019, P0335, P0336, P0337, P0338, P0339, P0385, P0386, P0387, P0388, and P0389. Engine starts sometimes but not others. If all internal sensor circuit resistance values are in line with specs, proceed to the next step. If you can obtain this type of scanner, it will be your best bet for diagnosing this code. Bank 2 represents the bank of the engine that does not contain the number one cylinder. That drove engineers to move away from carburetors and use fuel injectors and eventually to discontinue the use of distributors.
Technicians have reported that the presence of oil leaking on the outside of the engine often causes deteriorated insulation on wiring and may lead to shorted and loose connectors. This causes the Check Engine Light to be displayed on the dashboard and a failsafe mode enabled. That can cause you to replace a perfectly good sensor. P0385 Description The Crankshaft position sensor also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. Older engines relied on either a timing chain or timing gears to synchronize the camshaft to the crankshaft.
This information is used by the Electronic Control Module to control ignition and fuel injection. This information is an example of our investigations and findings and is not a definitive procedure. They , but they can be difficult to get to in order to service them. Some scanners also feature a and an oscilloscope with integrated test leads. Broken crankshaft reluctor rings or missing teeth may also cause this code to be set. Wiring Issues Due to the location of the crankshaft position sensor, it is prone to damage.

The error code P0340 simply means that the computer has completely sent a signal to the camshaft position sensor however it does not see the right signal that is being returned from the sensor. The camshaft position sensor senses the piston position. As the crankshaft rotates, the reluctor wheel teeth interrupt a magnetic field produced by a magnet within the sensor. Amazon Tracking Pixel Some articles display amazon products as part of the Amazon Affiliate program, this pixel provides traffic statistics for those products.
What are the symptoms of code P0385? The Crankshaft Position Sensor faces the gear teeth of the flywheel and detects the crankshaft position signal. This information is used by the Engine Control Module to control ignition and fuel injection. It rises back to 12 volts when the pin leaves the sensor head. In this case, you may experience hard starting, rough idle, or poor acceleration. Is the resistance of the sensor within the specs? In this case 12 volts. Once located, visually inspect the connectors and wiring. If the engine still runs, you will hear it.
This is one of the reasons why the changing gap causes the magnetic field near the sensor to change. If you notice this going over bumps, check the wiring harness to the sensor for chaffing. In Kia Rio, these wires are as shown in Fig. Disconnect the electrical connector, then remove the retaining bolt s. The purpose of this test is to check the condition of the wire harness. Again, check the wiring diagram found on for your vehicle.
Along with this information is the exact rotational speed and position of the crankshaft. Look for unexpected spikes or glitches in the waveform pattern. This information is used by the Electronic Control Module to control ignition and fuel injection. How does a crankshaft position sensor work? There are other causes as well. Technicians should whenever possible gain access to the test circuit without damage to seals and insulation. What causes the P0335 code? After that it would be prudent to look at the wiring harness plug at the sensor itself. With some vehicles, the engine may start to run poorly then die and not restart.
Google DoubleClick Google provides ad serving technology and runs an ad network. One of the most common symptoms of a bad reluctor ring is going to be a rattling sound. The Cam Mechanical Circuit spans from the Intake Camshaft, to the Camshaft Timing Chain, to the Exhaust Camshaft, to the Camshaft Sprocket. General connection advice PicoScope offers a range of options within the test kits. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. HubPages ® is a registered Service Mark of HubPages, Inc.
This progression of completing and interrupting the camshaft position sensor circuit produces a waveform pattern. Once you have cleared the sensor, you can clear the trouble code and restart your car Test Pin Combinations are: Pins 2 — 3 Pins 1 — 2 Pins 1 — 3 How to Fix To fix the engine from this error code, use a scan tool and inspect whether the engine is cranking or running. If you want to measure the signal voltage, try '3. No data is shared unless you engage with this feature. If the waveform seems normal, proceed to the next step.
