The Honda civic crankshaft place sensor is a part that’s situated under your timing assembly and placed to the engine alongside the crankshaft snout. This sensor is mainly responsible for informing your Honda ECU of the existing engine speed, or RPM. There is no this sensor the ECU will certainly not have the ability to operate the engine, and also it may shut off unexpectedly.

This sensor is likewise known as the Honda Civic Crankshaft speed fluctuation sensor as well, and also should no be perplexed with the recommendation sensor inside your distributor. For information on converting your VTEC Honda to operation on a distributorless ignition, examine our handy guide here.

Today we are looking in ~ the OBDII trouble code P0335 in a 1999 Honda public EX and also showing you just how to replace or service your Honda civic crankshaft position sensor. If your civic is an automatic your 1.6 D16 engine could shut off at speed, leaving friend without power steering or brake assist.

If your breakdown Indicator lamp (MIL) is lit and showing a P0335 problem code, you need to stop driving her Civic automatically until you service it. The D16 crankshaft sensor is placed near the crank gear and is design to read the high and also low spots. This provides the ECU through the proper signal compelled to orchestrate combustion.

This EX crankshaft position sensor may be a different component number than the no VTEC version of the Civic, but the replacement procedure is the same.

This Honda civic has a OBDII DTC trouble code of P0335 Honda’s specific language for this trouble password is Crank Sensor Malfunction. If you have a no start public or a Honda that’s no starting, try checking her crank shaft position sensor indigenous the loom located behind the front timing cover.

Where is Honda public crank place sensor located?

Like most SOHC civic engines, the crank engine sensor is an installed to the front oil pump assembly. The sensor is mounted to check out the teeth on your crankshaft gear. This hall result sensor is exactly how your Honda public ECU determines engine speed and also it’s associated by way of a two pin connector the runs come the earlier of your engine.


If you space planning to readjust your Honda public timing belt anytime soon, it could be a an excellent idea to complete both jobs at the exact same time. Because replacing this public crankshaft place sensor is reasonably easy once you have the timing assembly apart, you will certainly not need more work to remove it.

If you do should raise your public to remove your public crankshaft sensor instead of test it, make sure to lift and also secure your automobile carefully.

When increasing your Honda Civic, always use the proper safety measures and use too much caution. Performing a Honda Civic crankshaft place sensor test is basic using a multimeter. If you don’t know what a multimeter is, inspect our short article here for part tips.


What is 1.6 liter Honda civic crankshaft place sensor part number?

This public EX crankshaft sensor is part number 37500-P2F-A01 and it’s placed to the prior oil pump through a 10mm bolt. If your public is not starting and you have currently tested your crankshaft sensor, skip front to the removal procedure of the guide.

What is the civic EK crankshaft fluctuation sensor wiring schematic?

We’ll be testing your CKF in her Honda public EK by experimentation for power and ground, to make certain that it’s gift powered. If girlfriend do have power and ground in ~ the wires in question, chances are you have a break or intermittent wiring issue, or her sensor is failing.


To test her CKF because that power, disconnect the sensor and use your multimeter come probe pen 2. Pin 2 is a yellow/black wire that powers your crank sensor in your Civic. Get into her Civic and insert the key into the ignition, and also turn to the “ON” position.

Touch the black lead of her multimeter come the an adverse probe of her battery and also gently check the prior of the ENGINE side of the harness. Girlfriend should have power in ~ this wire, which way that your main relay is correctly powering her sensor.

How carry out I test Honda public crankshaft fluctuation sensor?

The trial and error procedure to measure the internal resistance of your hall effect Honda civic CKF sensor is easy and also straightforward. If your ignition is turned come the “ON” position, go ahead and remove the vital now and turn your ignition off.

Now utilizing your multimeter, you room measuring pen 1 and also PIN 3 for internal resistance. Between the terminal 1 and also terminal 3, you should have between 1.6 and also 3.2 Ω. If your inner resistance check out, relocate onto experimentation for continuity soil in the following segment of our DIY overview on trial and error your Honda civic crankshaft place sensor.

Testing your civic CKF for continuity

The next step in testing your crankshaft sensor is to examine for continuity in between your Civic’s chassis ground and the CKF sensor in ~ both terminal 3 and terminal 1. Making use of your multimeter, you have to make certain that there’s continuity between PIN 1 and your chassis ground, and PIN 3 and the ground. civic crankshaft fluctuation sensor checks out okay yet inspect engine irradiate won’t go away

This is a common issue and usually associated to damages in her ECU harness. To inspect this, you will be repeating the interior resistance test, yet AT THE ECU this time. Making use of your multimeter, you will certainly be measuring pen 1 and PIN 11 top top the 31 pen connector on her ECU.


Checking the Crankshaft position Sensor because that Power

Insert the key into the ignition and turn come the “ON” position, however do not start the vehicle. Unplug your D17 Honda civic crankshaft place sensor connector.

Use an extension wire native the negative post on your battery, and also connect it to the black color lead of her multimeter. Tenderness probe the former of the crankshaft position sensor at pin C or the yellow/black wire. You are looking for 12 volts DC here at this wire.

Next inspect PIN B or the center wire because that ground through reversing the wires and checking the front of the brown/yellow wire. Never pressure the pointer of your multimeter probe down into the slot of your connector.

If you have actually power and also ground in ~ these 2 wires, and there’s no sign of any kind of damage to your signal cable (PIN A – BLUE) then opportunities are girlfriend will have to replace your crankshaft place sensor.

If your sensor is not functioning correctly, friend will require to check the condition of her Honda public main relay.


Where perform I test civic ECU for CKF signal?

If your crankshaft fluctuation sensor tests good and appears okay at the plug, the following step is to trace earlier the SIGNAL wires for her CKF sensor. These run connector C on your SOHC Honda ECU, or the 31 pin key plug located at the ECU harness.


Check your passenger next kickpanel come trace earlier the wiring indigenous the 31 pen connector.


There are four signal wires girlfriend will want to inspect when her Honda civic won’t start. These are detailed below in the wiring schematic, and also require you to test the continuity between the sensor side and your ECU.


The 4 wires in inquiry are highlighted, and also broken the end for you here;

PIN 1 – color BLUE / RED – CKF p SensorPIN 3 – shade GREEN – TDC SensorPIN 4 – color YELLOW – CYP SensorPIN 2 – color BLUE – CKP Sensor – internal to civic distributor

Intermittent wiring concerns can be frustrating, therefore be patience to find your issue. Remember to examine your wiring and also the ECU wiring for any type of frayed wires or exposed wiring that might be subject to wire rot or damage. If friend detect any suspicious part of wiring, make sure to snip out carefully to remove and rewire.

Always use exact same gauge and style that wire as soon as replacing her damaged section of wiring harness in her Civic.
