Question about Cars & Trucks im getting codes p0300 p1168 p1051 when i took it to advanced. Just wanna know what they mean and what might need to be replaced under the hood. It's a 2004 Nissan titan, V8 4X4. It's not having any "symptoms" other than the service engine soon light on and blinking.

SOURCE: service engine light

Good Day,

Code P0102 indicates MAF(Mass Air Flow) sensor circuit, low frequency detected

Code P0300 indicates Random Cylider miss fire, meaning missfire in more than one cylinder

The misfire could be a result of the mas air flow sensor being faulty.

Hope this helps for now

Let me know what size motor and if it's 2wd or 4wd and I can get detailed instructions for replacing

Assuming the plugs and wires have been changed. I would look at the bottom of the coil pack. They tend to crack and short out.

Or if it's got coil packs they will also crack and short out.

SOURCE: Coolant Temp Sensor

The sensor is located on the drivers side engine block...although you can see if from looking from the top of the engine, you would have to get under the vehicle and look up to replace it. Be aware that it takes a special tool to unscrew the old one and screw in the replacement.

I have the same car and if the gas cap is loos for any reason the service engine light will come on so check that. If it is it will turn off in a few days after you tighten it.
