Are you a Jeep owner with a four-liter engine, particularly a Jeep Cherokee Sport? If you’ve been experiencing the check gauges light coming on and low oil pressure, I’ve got a quick and inexpensive fix for you. Let’s dive in.
Upon starting the engine, you may notice the oil pressure is fine at 40, but as the engine temperature increases, the oil pressure drops, triggering the check gauges light, especially at idle. The good news is that in most cases, this issue is simply caused by a faulty oil pressure sensor.
Fixing the Issue
To fix this, locate the oil pressure sensor above the oil filter and beside the distributor. Disconnect the wire connector from the sensor and remove the sensor using a 1 and 1/16 deep socket or an adjustable wrench.
Upon inspection, if you find oil inside the electrical connections, it indicates a faulty sensor. While some suggest cleaning the sensor, it’s recommended to replace it with a new one, which costs around $20.
When installing the new sensor, ensure the electrical connector is securely in place and add new oil if needed. For this particular engine, Kirkland 15W40 oil is recommended due to its high zinc levels, providing excellent lubrication for these older Jeep engines with a capacity of six quarts.
Verifying the Fix
After the replacement, take your Jeep for a drive and monitor the oil pressure. With the engine temperature at 210, the oil pressure should remain between 40 and 50, indicating a successful fix.
