What are the different types of engine sensors?
1 Coolant Temperature Sensor (CTS) 2 Intake Air Temperature Sensor (IAT) 3 Mass Airflow Sensor (MAF) 4 A Manifold Absolute Pressure Sensor (MAP) 5 O2 Sensors (Lambda) 6 Knock Sensors 7 Crankshaft Sensor 8 Camshaft Position sensor 9 Fuel Temperature Sensor 10 Fuel Pressure Sensor
Where does reduced engine power warning come from?
The reduced engine power warning message can come on your car or truck. Today’s vehicles are for the most part completely electronically controlled. From every button and switch on the dash down to the ‘fly-by-wire’ throttle control system. Back in the day, before these electronically controlled throttles, everything was cable actuated.
What are error codes for mass air flow sensor?
For doing so you only need to connect your code reader and turn the ignition key on (engine off), a state usually known as KOEO. Common error codes include P0299 (if turbocharger is fitted), P0300, P0101, P0102 and P0171.
Can a bad mass air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.
Can a check engine light code be troublesome?
Oxygen Sensors, otherwise referred to as O2 Sensors, and their related check engine light codes, can be troublesome at the very best! Today we discuss the design and function of these sensors, and some of the pitfalls encountered during the diagnosis of their related fault codes.
Why are so many no code sensor failures?
Because I’ve found that many no-code sensor failures can be caused by a bad battery wiping out the keep-alive memory during cranking, it’s very important at this time to check battery state-of-charge (SOC) and condition. It’s also best to let the vehicle cold-soak overnight and test from a cold start-up the next morning.
Can a check engine light be an oxygen sensor?
It seems as though the check engine light and O2 Sensor codes have always gone hand in hand. I can’t even begin to tell you how many perfectly good sensors I’ve seen replaced for a rich/lean code, or as a cure to a service engine light that comes and goes. Fact is, when oxygen sensors were first being used, they did tend to fail.
What does the O2 sensor delayed response code mean?
The OBD-II code P015b indicates the PCM has detected a delayed response from the bank 1 sensor 1 oxygen (O2) sensor. If your scanner logs this code, the guide below will help you address it. What Does the P015B Code Mean?
