The Honda civic crankshaft place sensor is a component that’s situated under her timing assembly and mounted to the engine next to the crankshaft snout. This sensor is mostly responsible because that informing your Honda ECU that the current engine speed, or RPM. Without this sensor the ECU will not be able to operate the engine, and also it might shut off unexpectedly.

This sensor is additionally known as the Honda Civic Crankshaft rate fluctuation sensor together well, and also should no be perplexed with the referral sensor inside your distributor. For details on converting her VTEC Honda to operation on a distributorless ignition, inspect our handy guide here.

Today we are looking at the OBDII trouble code P0335 in a 1999 Honda public EX and also showing you just how to change or service your Honda civic crankshaft place sensor. If your civic is one automatic your 1.6 D16 engine can shut off at speed, leaving girlfriend without strength steering or brake assist.

If your malfunction Indicator lamp (MIL) is lit and showing a P0335 problem code, you should stop driving her Civic instantly until you organization it. The D16 crankshaft sensor is mounted near the crank gear and also is draft to review the high and low spots. This gives the ECU v the appropriate signal compelled to orchestrate combustion.

This EX crankshaft position sensor may be a different component number 보다 the no VTEC versions of the Civic, yet the instead of procedure is the same.

This Honda public has a OBDII DTC trouble code of P0335 Honda’s certain language for this trouble password is Crank Sensor Malfunction. If you have a no start civic or a Honda that’s not starting, try checking her crank shaft position sensor from the loom located behind the front time cover.

Where is Honda public crank position sensor located?

Like many SOHC civic engines, the crank engine sensor is an installed to the former oil pump assembly. The sensor is placed to read the teeth on her crankshaft gear. This hall impact sensor is exactly how your Honda civic ECU identify engine speed and it’s linked by method of a two pin connector that runs come the ago of her engine.


If you are planning to change your Honda public timing belt anytime soon, it can be a an excellent idea to finish both work at the very same time. Since replacing this public crankshaft place sensor is reasonably easy when you have the timing assembly apart, you will certainly not need more work to eliminate it.

If friend do have to raise your civic to remove your public crankshaft sensor rather of check it, make certain to lift and also secure your automobile carefully.

When increasing your Honda Civic, constantly use the ideal safety measures and also use excessive caution. Performing a Honda Civic crankshaft position sensor test is basic using a multimeter. If friend don’t understand what a multimeter is, examine our post here for part tips.


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

This civic EX crankshaft sensor is part number 37500-P2F-A01 and it’s placed to the front oil pump by a 10mm bolt. If your public is not beginning and friend have already tested your crankshaft sensor, skip front to the removal process of the guide.

What is the civic EK crankshaft fluctuation sensor wiring schematic?

We’ll be trial and error your CKF in her Honda public EK by trial and error for power and ground, to make sure that it’s being powered. If you do have actually power and also ground at the wires in question, chances are you have a rest or intermittent wiring issue, or your sensor is failing.


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

Touch the black lead of your multimeter come the an adverse probe of her battery and gently test the former of the ENGINE next of the harness. You should have power in ~ this wire, which method that your key relay is properly powering her sensor.

How execute I test Honda civic crankshaft fluctuation sensor?

The trial and error procedure to measure the inner resistance of her hall impact Honda public CKF sensor is easy and straightforward. If her ignition is turned to the “ON” position, go ahead and also remove the key now and turn your ignition off.

Now using your multimeter, you space measuring pin 1 and PIN 3 for interior resistance. In between the terminal 1 and also terminal 3, you need to have in between 1.6 and 3.2 Ω. If your interior resistance check out, move onto experimentation for continuity soil in the next segment of our DIY guide on trial and error your Honda public crankshaft position sensor.

Testing your civic CKF because that continuity

The next step in testing your crankshaft sensor is to check for continuity in between your Civic’s chassis ground and also the CKF sensor at both terminal 3 and also terminal 1. Utilizing your multimeter, you need to make certain that there’s continuity between PIN 1 and also your chassis ground, and also 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 also usually related to damages in her ECU harness. To examine this, you will be repeating the internal resistance test, but AT THE ECU this time. Using your multimeter, you will be measuring pin 1 and also PIN 11 ~ above the 31 pin connector on her ECU.


Checking the Crankshaft position Sensor for Power

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

Use an expansion wire indigenous the negative post on your battery, and also connect it to the black lead of her multimeter. Tenderness probe the former of the crankshaft place sensor at pen C or the yellow/black wire. Friend are in search of 12 volts DC here at this wire.

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

If you have power and also ground in ~ these two wires, and also there’s no sign of any kind of damage to your signal wire (PIN A – BLUE) then possibilities are friend will need to replace your crankshaft position sensor.

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


Where do I test public ECU for CKF signal?

If your crankshaft fluctuation sensor tests an excellent and seems okay in ~ the plug, the next step is come trace earlier the SIGNAL wires for your CKF sensor. These operation 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 pin connector.


There are four signal wires you will desire to inspect when her Honda public 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 four wires in question are highlighted, and also broken out for girlfriend here;

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

Intermittent wiring problems can be frustrating, for this reason be patient to situate your issue. Psychic to check your wiring and the ECU wiring for any kind of frayed wires or exposed wiring that may be subject to wire rot or damage. If you detect any kind of suspicious sections of wiring, make certain to snip out very closely to remove and rewire.

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