MAINSHAFT SPEED SENSOR FOR 1996 HONDA ACCORD

This car is known for bad Instrument Clusters. Not to say that it is out of the question that your speed sensor could be bad... But 75% of the time it is the Cluster in the 1996-1997 Accord.. Car Part com Used Auto Parts Market

I believe that's a Speed Sensor issue.

Diag:
1. Ensure mainshaft and countershaft speed sensors are installed properly. Disconnect mainshaft speed sensor harness connector. Using a DVOM, measure resistance between sensor terminals.

2. If resistance is not 400-600 ohms, replace mainshaft speed sensor. If resistance is 400-600 ohms, disconnect 25-pin PCM harness connector "B". Check for continuity between ground and 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

3. If continuity is present, repair short to ground in Red or White wire between PCM and mainshaft speed sensor. If continuity is not present, reconnect mainshaft speed sensor harness connector. Measure resistance between 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

4. If resistance is not 400-600 ohms, go to next step. If resistance is 400-600 ohms, go to DTC
P0720 (FLASH CODE 9) . Check for loose PCM harness connectors. Replace PCM with a
known-good unit if necessary.

5. Disconnect mainshaft speed sensor harness connector. Check Red wire for continuity between 25-pin PCM harness connector "B", terminal No. 15 and mainshaft speed sensor harness connector. If continuity is present, go to next step. If continuity is not present, repair open in Red wire between 25-pin PCM harness connector and mainshaft speed sensor
harness connector.

6. Check White wire for continuity between 25-pin PCM harness connector "B", terminal No. 14 and mainshaft speed sensor harness connector. If continuity is present, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary. If continuity is not present, repair open in White wire between 25-pin PCM harness connector and mainshaft speed sensor harness connector.

Speed Sensor probably. Try:
1. Ensure mainshaft and countershaft speed sensors are installed properly. Disconnect mainshaft speed sensor harness connector. Using a DVOM, measure resistance between sensor terminals.

2. If resistance is not 400-600 ohms, replace mainshaft speed sensor. If resistance is 400-600 ohms, disconnect 25-pin PCM harness connector "B". Check for continuity between ground and 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

Measure resistance between 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

4. If resistance is not 400-600 ohms, go to next step. If resistance is 400-600 ohms, go to DTC

5. Disconnect mainshaft speed sensor harness connector. Check Red wire for continuity between 25-pin PCM harness connector "B", terminal No. 15 and mainshaft speed sensor harness connector. If continuity is present, go to next step. If continuity is not present, repair open in Red wire between 25-pin PCM harness connector and mainshaft speed sensor
harness connector.

6. Check White wire for continuity between 25-pin PCM harness connector "B", terminal No. 14 and mainshaft speed sensor harness connector. If continuity is present, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary. If continuity is not present, repair open in White wire between 25-pin PCM harness connector and mainshaft speed sensor harness connector.

they are inside the wheel hub/ wheel bearing

i found a detailed description on utube calledYouTube - 1AAuto.com Replace Install Vehicle Speed Sensor VSS Honda Accord Civic Odyssey Acura CL TL 1992-01

good luck

I changed my speed sensor but it did not resolve the problem still looking 4 a solution

It is the vehicle speed sensor either in the side of the transmission or by the engine. It is a speed sensor issue.

What sensor are you try to look for?
here is the list of all the sensors for 97 honda civic EX
1.Countershaft Speed sensor
Driven Pulley speed sensor
Engine Coolant Temperature Sensor
Front wheel sensor
Fuel Tank Pressure Sensor
Intake Air Temperature Sensor
Knock Sensor
Mainshaft speed sensor
Manifold Absolute pressure (Map) sensor
Primary Heated Oxygen sensor
Rear Wheel sensor
Secondary Gear shaft speed sensor
Throttle Position sensor
Vehicle speed sensor.

I hope this can help you, please put something on the ratting. good luck.

on the trans, its underneath the battery, in-line with the battery clamp toward the front of the car.

If you are talking about just plugging into the speed sensor yes. A VTEC and NON-VTEC are one and the same.
