What is the TPS

100

This sensor reports the temperature of the area surrounding the combustion chamber for more efficient mixture of fuel and air and it's subsequent burn

What is the ECT sensor

100

This sensor is supposed to cycle from high voltage (1Volt) to low voltage (.1volt) when the engine is running correctly

What is the front O2 sensor B1s1 and B2s1
100

this is where the DLC should be located

What is under the drivers side dash

100

This type of powertrain DTC will not usually cause the MIL to illuminate

What is a pending DTC

200

It reports the position of the accelerator pedal

what is the APP sensor
200

This sensor reports the speed of the crankshaft and it's position relative to TDC of cylinder #1

What is the CKP sensor

200

This sensor is responsible for telling the ECM if the catalytic converter is functioning properly

What is the rear O2 sensor (b1s2 and b2s2)

200

This digit in the 17 digit VIN number represents the model year of the vehicle

What is the 10th digit

200

What type of trouble code is this? 

What system and is it generic or manufacturer specific? 

                              P0128

Generic powertrain code

300

This sensor reports the amount of air entering the intake if you do not have a MAP sensor

What is the MAF sensor

300

this sensor works with the CKP to allow proper injector and ignition synchronization with respect to the compression stroke of TDC

what is the CMP sensor

300

This sensor is looked at by every computer on the car to know how fast you are driving

What is the VSS sensor

300

This digit in the VIN number represents the engine type in the 17 digit VIN number

What is the 8th digit

300

The powertrain sub systems will not allow a DTC to set when a fault is present until after this resets to "READY"

What is a monitor?

400

This sensor reports the amount of vacuum in the intake to allow the ECM to compensate for load by adding more fuel when engine vacuum drops and vice versa

What is the MAP sensor

400

This sensor is responsible for reporting misfires

What is the CKP sensor

400

This is how computers read sensors. (the type of info that is provided by the sensor and translated into data)

What is 5 volt reference and/or sensor feedback/return

400

This vin digit represents the body type/style of the vehicle in the VIN number

On cars what is the 4th digit

On trucks what is the 5th digit

400
This is the most important step in the diagnostic process. (hint: it's not the tsb search)

what is performing the visual inspection

500

This sensor is responsible for letting the ECM know how much air per volume is present in the intake as it passes the MAF. It indirectly reports the weight of the air by reporting something else

What is the IAT sensor

500

If this sensor fails the car will continue to run but it has only a 1 in 3 chance of restarting

what is the CMP sensor

500

This is the code for a random multiple misfire

what is a P0300

500

When working on newer cars (under 3 years) which step in the diagnostic process helps you fix 30-70% of the issues you will encounter?

What is searching for TSB's

500

This is the first step in the diagnostic process and performing it prevents you from chasing ghosts

What is verifying the complaint
