Understanding the P1690 Metering Oil Pump Stepping Motor Circuit Malfunction
Before we dive into the solution, let’s first understand what this error code means. The P1690 code indicates that there is a malfunction in the metering oil pump stepping motor circuit. This circuit is responsible for controlling the oil pressure in the engine. When the circuit malfunctions, it can cause the oil pressure to drop, leading to engine damage.
Step-by-Step Guide to Fixing the P1690 Metering Oil Pump Stepping Motor Circuit Malfunction
1. Check the Oil Pressure Sensor
The first step in fixing this issue is to check the oil pressure sensor. This sensor is located on the engine block and is responsible for monitoring the oil pressure. If the sensor is faulty, it can cause the P1690 code to appear. To check the sensor, use a multimeter to test the resistance. If the resistance is outside of the manufacturer’s specifications, replace the sensor.
2. Inspect the Wiring
If the oil pressure sensor is functioning correctly, the next step is to inspect the wiring. Look for any signs of damage or corrosion. If you find any issues, repair or replace the wiring as needed.
3. Check the Metering Oil Pump
If the wiring is in good condition, the next step is to check the metering oil pump. This pump is responsible for regulating the oil pressure in the engine. To check the pump, remove it from the engine and inspect it for any signs of damage or wear. If the pump is damaged, replace it with a new one.
4. Replace the Stepping Motor
If the pump is functioning correctly, the issue may be with the stepping motor. This motor is responsible for controlling the oil pressure in the engine. To replace the motor, remove the old one from the engine and install a new one.
