What causes code P1259?
The most common cause for Error Code P1259 or VTEC system malfunction is low oil pressure. Thus, make sure you check your oil if it’s due for service. Change oil and filter if necessary. Lastly, you could have a restricted VTEC solenoid passage, or faulty VTEC solenoid or wiring.
When do I get an 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. As with other error codes, Error Code P1259 activates the Check Engine light and registers the code to the vehicle’s memory 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.
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.
When to set code p1259 in Powertrain Control Module?
On applications that use this definition, code P1259 is set when a break in communication between the immobilizer module and the PCM (Powertrain Control Module), or between the transponder key and immobilizer module occurs.
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 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 VTEC system error code p1259?
This error code can be caused by multiple of factors, such as: 1 Low oil pressure or low engine oil level 2 Defective VTEC solenoid 3 Open or shorted VTEC harness 4 Poor electrical connections in the VTEC circuit 5 Defective VTEC oil pressure switch More
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…
