Product Update: Oil Pressure Switch
(Supersedes 92-003, dated January24, 1992) .


BACKGROUND

Oil pressure switches are supplied to Honda by two companies. A quantity of switches supplied by one company late in 1991 have a manufacturing defect that can cause them to seep oil at the joint between the plastic cap and the metal case.

VEHICLES AFFECTED

Civic 1.5: from VIN JHMEG8 ... NS011475 to JHMEG8.. . NS017724

Civic 1.6: from VIN JHMEH9... NS002766 to JHMEH9 ... NS003622

Accord: from VIN JHMCB7 ... NC043270 to JHMCB7 ... NC049414

Prelude S: from VIN JHMBA8 ... NC003023 to JHMBA8 ... NC005052

Prelude Si: from VIN JHMBB2 ... NC004968 to JHMBB2 ... NC008227

NOTE:
Only vehicles within the above VIN ranges need inspection. Switches with green plastic ends on vehicles outside the ranges are not a problem.

CUSTOMER NOTIFICATION

Owners of affected vehicles will be contacted by mail and asked to take the car to a dealership for repair. The text of the customer letter is on the back of this service bulletin.

DEALER STOCK

Dealers should also inspect and repair any affected vehicles in their stock during PDI.

CORRECTIVE ACTION

Inspect the oil pressure switch to determine if it has a green plastic end or black plastic end. If it is green pastic, replace it with the switch listed under PARTS INFORMATION.


1. Raise the car on a hoist.





2. Locate the oil pressure switch by the oil filter. Inspect the plastic end to see what color it is. On the Prelude Si, the wire is bolted to the switch so you must fold back the rubber boot to see the end. On all other models, remove the wire and boot by pulling them straight off.


3. a) If the switch has a black plastic end, reconnect the wire and boot and go to step 4.

b) If the switch has a green plastic end, replace it with a new unit. Coat the threads with a 3 mm wide bead of Liquid Gasket (P/N 08718-0001) before installation. Torque the switch to 1.8 kg-m (13 lb.ft).

4. Lower the hoist. Check the engine oil level and add as needed.





5. Center punch a completion mark over the last digit in the VIN in the engine compartment.

Product Update: Oil Pressure Switch


Dear Honda Owner:


A few 1992 Honda automobiles were produced with an engine oil pressure switch that will seep oil. Our records indicate that your Honda may have one of these switches.

An updated oil pressure switch is available. Please call your dealer and make an appointment to have your Honda inspected. If he determines that the oil pressure switch is not up to specifications, he will replace it with an updated unit. This update will be done free of charge.

We apologize for any inconvenience this product update may cause you, however, our main concern is your continued satisfaction with your Honda automobile.


Respectfully,
AMERICAN HONDA MOTOR CO., INC.
