crank position sensor in 95 civic si
so where exactly is the crank position sensor? im throwing a CEL # 4. i checked wires at the ecu, engine harness, and distributor and they look good, no corrosion.
im guessing i have to replace the crank position sensor or replace the whole dizzy as a unit, correct?
my friend says to replace the icm? help please! car is at 1200rpms at idle and smells like it is dumping alot of gas.

Measure the resistance across the two terminals of the CKP sensor. It should read 350-700 Ohms. If the resistance is fine test the same two terminals for a short.

There is a test procedure
• Disconnect the 8pin connector from the distributor
• Measure the resistance between sensor terminals B & F (ECU terminals B15 BLU/GRN wire & B16 BLU/YEL wire)
• If the resistance is not between 350Ω & 700Ω replace the distributor.
• If the resistance is between 350Ω & 700Ω - Check for continuity to body ground on both B & F terminals.
• Does continuity exist
Yes - replace distributor
No
• Test the ECU

do i do the test with the ignition to II? one probe to terminal B and other to ground? or what??

Re: crank position sensor in 95 civic si
The tests are done with the key off.
Resistance test - one probe to B, one probe to F
Short tests - (1) one probe to B, one probe to ground; (2) one probe to F, one probe to ground

Re: crank position sensor in 95 civic si
ok so here is the results.
resistance at
2000k-goes to a number then back to zero
200k- .3
20k-.40
2000- 408
200-151.5 then 1 .
am i doing it right? not to sure what to put the multimeter at for the short test. but im guessing the --> combined with the +, right?

Re: crank position sensor in 95 civic si
The 2000 Ohm scale is the correct one to use for the resistance test. The resistance of the CKP sensor is 408 Ohms, which is within spec (=good). Now do the short tests. Use the 200 Ohm scale for the short tests.

Re: crank position sensor in 95 civic si
ok i just did the continuity test set at ->+ and my multimeter stays at 1 during tests with both terminals. it didnt even change

Re: crank position sensor in 95 civic si
i used that setting above. red probe to terminal B and blk probe to dizzy housing, then to chassis, then to random bolts. they showed nothing on the multimeter so i went and checked terminal F, same results

Re: crank position sensor in 95 civic si
Start here:
Plug the distributor connector back in and then unplug ECU connector B. Set the meter to read Ohms on the 2000 scale. What is the resistance between ECU connector terminals B15 and B16?

Re: crank position sensor in 95 civic si
ok ohms set at 2000 test terminal B15 and B16 with dizzy plugged back in, results are 397.

Re: crank position sensor in 95 civic si
Problem solved!! Thank you Ron!! There was a break in side the wire for terminal b15 at the ecu plug, not visible from the outside. The break was real close to the terminal pin, not making contact with the ecu pin (probably cause I take out The ecu out every night). Anyway thanks Ron for helping me diagnose the problem and on top of that keeping me from throwing money at random parts.

Re: crank position sensor in 95 civic si
The resistance of my ckp is 347. Is this a bad sensor then? The dizzy worked before I pulled the cylinder head to replace the valves now the car starts for second, dies, and the code 4 turns on
