The Honda civic crankshaft place sensor is a part that’s located under her timing assembly and placed to the engine alongside the crankshaft snout. This sensor is generally responsible for informing her Honda ECU of the existing engine speed, or RPM. Without this sensor the ECU will certainly not be able to operate the engine, and it might shut off unexpectedly.

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

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

If your malfunction Indicator desk lamp (MIL) is lit and also showing a P0335 problem code, you have to stop driving her Civic immediately until you organization it. The D16 crankshaft sensor is mounted near the crank gear and also is designed to review the high and low spots. This offers the ECU v the ideal signal forced to orchestrate combustion.

This EX crankshaft position sensor might be a different component number 보다 the no VTEC execution of the Civic, but the replacement procedure is the same.

This Honda public has a OBDII DTC trouble code of P0335 Honda’s specific language because that this trouble code is Crank Sensor Malfunction. If you have a no start public or a Honda that’s not starting, try checking your crank column position sensor indigenous the loom located behind the front timing cover.

Where is mine Honda civic crank place sensor located?

Like many SOHC civic engines, the crank engine sensor is mounted to the front oil pump assembly. The sensor is placed to check out the this on your crankshaft gear. This hall result sensor is just how your Honda civic ECU identify engine speed and also it’s associated by means of a 2 pin connector that runs to the ago of her engine.


If you room planning to change your Honda public timing belt whenever soon, it could be a great idea to finish both tasks at the same time. Since replacing this public crankshaft place sensor is relatively easy as soon as you have actually the time assembly apart, you will not need an ext work to eliminate it.

If friend do need to raise your public to remove your public crankshaft sensor instead of check it, make sure to lift and secure your auto carefully.

When increasing your Honda Civic, constantly use the suitable safety measures and also use too much caution. Performing a Honda Civic crankshaft position sensor test is simple using a multimeter. If you don’t recognize what a multimeter is, inspect our write-up here for part tips.


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

This public EX crankshaft sensor is part number 37500-P2F-A01 and also it’s placed to the former oil pump through a 10mm bolt. If your public is not beginning and you have currently tested her 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 your Honda civic EK by experimentation for power and also ground, come make certain that it’s gift powered. If girlfriend do have power and also ground in ~ the wires in question, possibilities are you have actually a rest or intermittent wiring issue, or her sensor is failing.


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

Touch the black color lead of her multimeter come the an adverse probe of her battery and also gently check the former of the ENGINE next of the harness. Friend should have power at this wire, which means that your key relay is properly powering her sensor.

How do I test Honda public crankshaft fluctuation sensor?

The testing procedure to measure the interior resistance of her hall impact Honda civic CKF sensor is easy and straightforward. If your ignition is turned come the “ON” position, walk ahead and also remove the vital now and turn your ignition off.

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

Testing your civic CKF because that continuity

The following step in trial and error your crankshaft sensor is to inspect for continuity between your Civic’s chassis ground and also the CKF sensor in ~ both terminal 3 and also terminal 1. Making use of your multimeter, you need to make certain that there’s continuity between PIN 1 and also your chassis ground, and also PIN 3 and also the ground. civic crankshaft fluctuation sensor checks the end okay however check engine light won’t go away

This is a usual issue and also usually related to damage in your ECU harness. To inspect this, you will certainly be repeating the internal resistance test, yet AT THE ECU this time. Making use of your multimeter, you will be measuring pen 1 and also PIN 11 ~ above the 31 pin connector on your ECU.


Checking the Crankshaft place Sensor for Power

Insert the an essential into the ignition and turn to the “ON” position, however do not start the vehicle. Unplug her D17 Honda civic crankshaft place sensor connector.

Use an extension wire indigenous the negative post on her battery, and connect it to the black lead of your multimeter. Gently probe the prior of the crankshaft place sensor at pin C or the yellow/black wire. You are in search of 12 volts DC here at this wire.

Next check PIN B or the middle wire for ground by reversing the wires and checking the prior of the brown/yellow wire. Never pressure the pointer of your multimeter probe down right into the slot of your connector.

If you have power and also ground at these two wires, and also there’s no authorize of any type of damage to her signal wire (PIN A – BLUE) then opportunities are you will must replace your crankshaft position sensor.

If your sensor is not working correctly, girlfriend will require to check the condition of your Honda civic main relay.


Where do I check civic ECU because that CKF signal?

If her crankshaft fluctuation sensor tests great and appears okay in ~ the plug, the following step is to trace ago 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 side kickpanel to trace back the wiring indigenous the 31 pin connector.


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


The four wires in question are highlighted, and broken out for girlfriend here;

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

Intermittent wiring issues can be frustrating, therefore be patient to situate your issue. Psychic to examine your wiring and also the ECU wiring for any type of frayed wires or exposed wiring that might be subject to cable rot or damage. If you detect any type of suspicious sections of wiring, make sure to snip out very closely to remove and rewire.

Always use exact same gauge and also style the wire once replacing your damaged ar of wiring harness in your Civic.
