KIA: Codes P0171, P0446, P0507 And P2187
This Kia Rio had the check engine light on with codes P0171, P0446, P0507 and P2187. Follow this Real Fix to see the diagnostic steps used to determine the actual fault.
VIDEO: Gasoline Direct Injection (GDI) Carbon Deposits And The Synthetic Oil Connection
Conventional oil that has high volatility will cause more vapors and make carbon deposits worse. Synthetic oil with low volatility can reduce vapors and prevent carbon from forming on the valves. Sponsored by Auto Value and Bumper to Bumper.
VIDEO: Diesel Exhaust Fluid Winter Tip
Andrew Markel shares a quick tip about diesel exhaust fluid and why the level sensor may show as low in the winter, even when it is topped off.
Electronically Controlled Thermostats: A New Take On Wax And Brass
An electronic thermostat can preemptively control the temperature the same way the fuel injection system can control the stoichiometric ratio in the combustion chamber by changing the pulse width of the fuel injector. By being able to control the temperature of the coolant, the engine management system can optimize engine performance so leaner combustion events can take place and cold start periods are minimized.
Saturn Tech Tip: Vehicle Fails Emissions Tests
State emissions tests need to be done, but when a vehicle does not pass the test the first time, where do you look? This Real Fix provides multiple diagnostic procedures that could lead you to the fault. Kiss that ugly engine coolant temperature sensor wiring harness damage goodbye and ensure that the Saturn passes the emissions test with flying colors.
