What does an oil can and wrench light mean on a 2007 Chevy Trailblazer?

On a 2007 Chevy Trailblazer, the simultaneous illumination of the oil can (low oil pressure) and wrench (Check Engine/Service Engine Soon) lights indicates a serious problem requiring immediate attention. Don't drive the vehicle until it's addressed.

The combination suggests a potential link between low oil pressure and another engine-related issue. The wrench light usually comes on due to a fault detected by the onboard computer. Since it's accompanied by the low oil pressure light, possible causes could include:

* Low oil level: This is the simplest explanation. Check your oil level immediately. Low oil leads to low oil pressure, causing significant engine damage if driven.

* Oil pump failure: The oil pump is responsible for circulating oil. A failing pump won't adequately lubricate the engine.

* Clogged oil filter: A blocked filter restricts oil flow, leading to low pressure.

* Leaking oil: An oil leak can drastically reduce oil level and pressure.

* Damaged or worn engine components: Internal engine damage (e.g., worn bearings) can also cause low oil pressure.

What to do:

1. Pull over immediately and turn off the engine. Continuing to drive with low oil pressure can cause catastrophic engine damage.

2. Check the oil level: Use the dipstick to ascertain if the oil is low. If it's extremely low, you'll need to add oil, but this doesn't fix the underlying problem.

3. Have the vehicle towed to a qualified mechanic. Do not attempt to drive it. A professional diagnosis is crucial to determine the exact cause and necessary repairs. The problem is likely more severe than just needing an oil top-off.

Ignoring these lights could result in expensive engine repairs or even a complete engine failure. Immediate action is necessary.
