Can you bypass VTEC solenoid?
This can be easily bypassed with a simple wiring trick: On your engine harness, locate the VTEC oil pressure switch plug/wire (this wire comes from OBD1 ECU pin D6). Do not cut the VTEC solenoid wire, simply connect the Vtec pressure switch wire to it.
Where is the VTEC system malfunction code p1259?
Re: VTEC System Malfunction code P1259 has appeared. (… Check your variable valve timing oil pressure switch, it’s located on the passanger side just before the intake manifold, also the solenoid may be dirty or bad. some people say to clean the screen but that requires removing the entire assembly where these two units are… Good luck
When is the p1259 code detected in a powertrain?
When is the P1259 code detected? 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.
What are the possible causes of Honda p1259?
P1259 Honda 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.
Where is the p1259 sensor located on a Honda Civic?
It should be noted though while that code P1259 specifically refers to a problem in the VTEC systems’ control/signal/monitoring circuit, some mechanical failure modes can contribute to this code being set and stored. Where is the P1259 sensor located? The image above shows the location of the VTEC oil control solenoid on a Honda Civic engine.
