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 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
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.
What do you need to know about Honda p1259?
P1259 Honda Description. 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…

What causes a PCM signal error code p1259?
The most common cause of code P1259 is flat batteries in keys, with abnormal system voltages caused by faults and defects in the charging system that could damage control modules following close behind.

What causes a Honda VTEC code p1259?
Nonetheless, some other common causes of code P1259 could include the following- Failed or failing PCM, but note that since this a rare event, the fault must be sought elsewhere before any control module is replaced
What does p1259 stand for in immobilizer code?
There are no codes directly related to P1259. Any problem such as abnormal input or system voltages, intermittent faults, or high resistances in any part of the immobilizer control circuit will set code P1259. Below are some examples of definitions of code P1259 that do not relate to the anti-theft system.
What is the VTEC oil pressure switch error code p1259?
Error Code P1259 is detected when there is a problem in the VTEC oil pressure switch or at the VTEC solenoid valve circuit. Common Symptoms. As with other error codes, Error Code P1259 activates the Check Engine light and registers the code to the vehicle’s memory system.
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.

What is the trouble code for Honda VTEC?
P1259 – VTEC system malfunction (Honda) Trouble Code Fault Location Probable Cause P1259 VTEC system malfunction Wiring, VTEC solenoid/pressure switch, E
What causes a VTEC system to malfunction?
NOTE: While there are some exceptions, the general rule is that if the code sets at, or just above idling speeds, the fault is caused by a general electrical issue, while if the code sets above about 4000 RPM, the fault almost invariably involves insufficient oil pressure, or a failure of the VTEC oil pressure sensor. None found.
