Hello, I would like to ask about a problem that I have with my check engine light. I have a Honda Civic 1997 and I went to put the machine to my car since the check engine light turned on, and the codes that the machine retreive were:
P1337 CSF Sensor no signal
P1336 CSF Sensor intermitent interruption
And would like to have and estimate of how much money it would be to have this problem solve, with the parts and labor I live in United States. Thank you, i´ll be waiting for the answer.

Cost repair would depend on what is wrong.

DTC P1336 & P1337: CRANKSHAFT SPEED FLUCTUATION (CKF) SENSOR
NOTE:
DTC P1336 indicates an intermittent interruption in CKF sensor circuit. DTC P1337 indicates no signal in CKF sensor circuit.

1. Perform PCM reset procedure. Start engine. If DTC P1336 and/or P1337 is indicated, go to next step. If DTC P1336 and/or P1337 is not indicated, problem is intermittent, system is okay at this time. Check for poor connections or loose wires between CKF sensor and PCM. Repair as necessary.

2. Turn ignition off. Disconnect CKF sensor 3-pin connector. Measure resistance between White and Blue wire of CKF sensor connector. If resistance is 1600-3200 ohms, go to next step. If resistance is not 1600-3200 ohms, replace CKF sensor.

3. Check for continuity between ground and CKF sensor connector White wire and Blue wire, individually. If continuity does not exist, go to next step. If continuity exists, replace CKF sensor.

4. Turn ignition off. Reconnect CKF sensor connector. Disconnect PCM 31-pin connector "C". See Fig. 3. Measure resistance between PCM connector "C" terminal C1 (Blue/Red wire) and terminal C11 (White/Red wire). If resistance is 1600-3200 ohms, go to next step. If resistance is not 1600-3200 ohms, repair open in wire(s) between CKF sensor and PCM.

5. Check for continuity between ground and PCM 31-pin connector "C" terminal C1. If continuity exists, repair short in wire(s) between PCM and CKF sensor. If continuity does not exist, substitute a known-good PCM and recheck. If symptom or problem goes away, replace original PCM.
