P1259 1996 HONDA CIVIC Possible Causes

  • Low engine oil level or oil pressure
  • Faulty Variable Valve Timing and Lift Electronic Control (VTEC) solenoid
  • VTEC Solenoid harness is open or shorted
  • VTEC circuit poor electrical connection
  • Faulty VTEC oil pressure switch

How is the P1259 1996 HONDA CIVIC code repair?

Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

Tech Notes

Make sure the oil level is good and it is not dirty, if the oil is dirty replace it with the correct oil weight. Dirty oil can clog the VTEC assembly so you might have to take it apart and and clean it (and replace the seals).

What is the cost to diagnose the P1259 1996 HONDA CIVIC code

Labor: 1.0

The cost to diagnose the P1259 1996 HONDA CIVIC code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

When is the code detected?

The P1259 is set when there is a problem in the VTEC Oil Pressure Switch circuit or VTEC Solenoid Valve circuit

Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)

P1259 1996 HONDA CIVIC Meaning

The Variable Valve Timing and Lift Electronic Control (VTEC) system activate the VTEC solenoid valve by the command from the Powertrain Control Module (PCM), and it charges/discharges the hydraulic circuit of the VTEC mechanism that is installed in the valve system to switch valve timing between Low and High. The PCM monitors oil pressure conditions in the hydraulic circuit of the VTEC mechanism according to the VTEC oil pressure switch downstream of the VTEC solenoid valve. If there is a disparity between oil pressure condition in the hydraulic circuit that is determined by the PCM command, and the oil pressure condition that is determined by the status of the VTEC oil pressure switch, the system is considered faulty and the P1259 code is stored.
