Question about Cars & Trucks
"Service engine soon" light came on in my 2009 Mitsubishi Gallant. Had it checked and the following code was given: "Radiator Sensor 2". What does that mean and how do I fix it?

Based on what the tech manuals say I would change the DPFE sensor for the EGR Valve, careful not to tear the special silicone rubber hoses that go to it from the exhaust, as a Ford dealer tech I saw these codes allot, and the DPFE sensor was almost always the issue or the hoses going to it.

This happens when the Engine Coolant Temperature (ECT) does not reach 75°C (167°F) despite sufficient engine warm-up time.
This happens usually when the thermostat/temperature sensor is faulty, and is bad for emissions and fuel consumption.
The repair cost may vary, even if themperature sensor is not an expensive part, after replacing the sensor there is need to reset the ECU (car computer module).

It NEVER was the camshaft sensor! Unless, you've removed the engine lately, which I doubt.
RUN to Advance Auto Parts and buy a can of "SeaFoam" and add to your gas tank per instructions...drive at least 100 miles and the problem should go away...IF it doesn't you'll have to replace the O2 sensors in the exhaust system...Any good mechanic should be able to do this for much less $$ than the dealership DO NOT go to the dealer for repairs!

you may have to drive it several days for the light to go off, or have the codes cleared. personally I would just drive it. if the computer tests it, and it passes the test, it will go off on its own.
