Scan tool PID's
It reports the position of the throttle plate
What is the TPS
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
This sensor is supposed to cycle from high voltage (1Volt) to low voltage (.1volt) when the engine is running correctly
this is where the DLC should be located
What is under the drivers side dash
This type of powertrain DTC will not usually cause the MIL to illuminate
What is a pending DTC
It reports the position of the accelerator pedal
This sensor reports the speed of the crankshaft and it's position relative to TDC of cylinder #1
What is the CKP sensor
This sensor is responsible for telling the ECM if the catalytic converter is functioning properly
What is the rear O2 sensor (b1s2 and b2s2)
This digit in the 17 digit VIN number represents the model year of the vehicle
What is the 10th digit
What type of trouble code is this?
What system and is it generic or manufacturer specific?
P0128
Generic powertrain code
This sensor reports the amount of air entering the intake if you do not have a MAP sensor
What is the MAF sensor
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
This sensor is looked at by every computer on the car to know how fast you are driving
What is the VSS sensor
This digit in the VIN number represents the engine type in the 17 digit VIN number
What is the 8th digit
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?
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
This sensor is responsible for reporting misfires
What is the CKP sensor
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
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
what is performing the visual inspection
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
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
This is the code for a random multiple misfire
what is a P0300
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
This is the first step in the diagnostic process and performing it prevents you from chasing ghosts
What is verifying the complaint
