[citation needed] Volvo had a light labeled "lambda", lambda sond being another name for oxygen sensor. This was done in order to remind the driver to change the oxygen sensor. Some American-built 1973–1976 Chrysler Corporation vehicles had a similar odometer-triggered reminder: "Check EGR", which was reset after service at a Chrysler dealership.
The 2009–11 Toyota vehicle recalls involved three separate but related recalls of automobiles by the Japanese manufacturer Toyota Motor Corporation, which occurred at the end of 2009 and the start of 2010. Toyota initiated the recalls, the first two with the assistance of the U.S. National Highway Traffic Safety Administration (NHTSA), after ...
The heart of the Mitsubishi's MVV system is the linear air–fuel ratio exhaust gas oxygen sensor. Compared with standard oxygen sensors, which essentially are on-off switches set to a single air/fuel ratio, the lean oxygen sensor is more of a measurement device covering the air/fuel ratio range from about 15:1 to 26:1.

A bad crank position sensor can worsen the way the engine idles, or the acceleration behaviour. If the engine is revved up with a bad or faulty sensor, it may cause misfiring, motor vibration or backfires. Acceleration might be hesitant, and abnormal shaking during engine idle might occur. In the worst case, the car may not start.
2004: The NHTSA sent Toyota a chart showing that Toyota Camry models with electronic throttle controls had over 400% more "vehicle speed" complaints than those with manual controls. [citation needed] 2005: Incident observed in a Toyota Camry. The cause was initially suggested to be a tin whisker, [27] however this was later proven not to be the ...
In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.
Dry sump engines in some drag racing cars use scavenging pumps to extract oil and gases from the crankcase. [18] A separator removes the oil, then the gases are fed into the exhaust system via a venturi tube. [citation needed]. This system maintains a small amount of vacuum in the crankcase and minimises the amount of oil in the engine that ...
It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms. Determining the most likely cause is a process of elimination—eliminating potential causes of a problem. Finally, troubleshooting requires confirmation that ...
