HiCustomer welcome to justanswer. My name is IKE.


Is your check engine light on?

Customer: replied 9 years ago.
Yes. Code is 1382 and 1259.

Okay, the service manual troubleshooting guide leads me to replacing the ECU, just as it always does, but this is seldom the problem. If you can, clear the code (pull the clock/back-up in the passengers dash fuse box fuse for 10 seconds with the ignition off) unplug the 4 pin connector on the back of the alternator and test drive the car again. If the DTC sets again, the distributor housing is bad. If it does not set again, have the alternator checked. A bad diode in the alternator can cause interference with the CYP sensor.



Here is a copy of a service news article that you can look at to check your VTEC code.


I know you probably can't hook it up to a tester, but you can connect pos and neg to the 2 pin connector momentarily to see if the VTEC solenoid is engaging. Listen for a light click noise from the solenoid.


On '98 Accord L4s with VTEC, DTC P1259 (VTEC

system malfunction) can set at idle or above 4,000 rpm:

  • If it sets at idle, the problem is with the VTEC pressure

switch circuit (switch, connectors, or wiring).

  • If it sets above 4,000 rpm, the cause is low oil pressure in

the VTEC system.

To find and correct the cause of the DTC, do this:

1. Use the PGM Tester to check the vehicle's freeze data

or snapshot data to see when the DTC was set.

  • If it set at idle, go to step 2.
  • If it set above 4,000 rpm, go to step 4.

2. Disconnect the 2P VTEC pressure switch connector,

and jump its two wires.

3. With the ignition switch ON (II), the PGM Tester

should show that the VTEC pressure switch is ON.

  • If the Tester says the switch is ON, the wiring and

connectors are OK, so the switch must be bad.

Replace the switch, clear the DTC, and return the

vehicle to the customer.

  • If the switch is OFF, check for an open circuit

between the switch and the ECM/PCM or between

the switch and ground. After you repair the open

circuit, recheck the switch, then clear the DTC, and

return the vehicle to the customer.

4. Remove the valve cover, and check for a loose center

head bolt on the intake manifold side. A loose bolt can

cause a drop in pressure in the VTEC system.

  • If the bolt isn't loose, go to step 5.
  • If the bolt is loose, torque it to 22 lb-ft (29 N⋅m),

turn it another 1/4 turn, and then turn it another 1/4

turn. If the bolt won't tighten, its threads are

probably stripped.

5. Remove the VTEC rocker arms, and inspect them for

sticking or missing synchronizer pistons or other valve

train problems that could cause an oil leak.

  • If you find any piston or valve train problems,

replace the faulty parts. Then clear the DTC, and

return the vehicle to the customer.

  • If the pistons and the valve train are OK, do the DTC

P1259 troubleshooting procedure on pages 6-7 thru

6-9 of the '98-99 Accord S/M.

Another thing to make sure of is that your car has the correct amount of oil in it. Low oil pressure will also cause a VTEC code.
