BEcause the Computer is generally programed to ignore the readings from the Lambda Sensor (Oxegen Sensor in North America) untilll the engine and the sensor warm up.
Once this delay passes the computer realizes there is a fault.
Need to know make/model/year, never seen a lambda symbol. The O2 sensor is a lambda sensor. If it is for that, it can give you bad performance/ fuel economy. In general if there is a light for what ever it is on the dashboard, you shouldn't drive too long with it on, for safety reasons (ex. tire light) or to prevent damage( check engine, low oil pressure light).
I just disconnect the battery terminal for a few minutes and then connect it again and the Lambda light goes off. Emmanuel Vella.
The Lambda warming light on the dashboard is a caution indicator. Essentially it's saying something needs to be checked. It's in need of immediate attention if it's in red.
Lambda sensors. The 3 leg symbol (upside down 'Y') is the greek lambda symbol
you need to take the car to garage . its normally a dead lambda or o2 sensor . easy fix
The term "warning light" tells you that you need to check something out.
Disconnect the battery for two minutes, then re-connect it.
These tests are used to monitor Myeloma and other Plasma Cell disorders.The Kappa and Lambda Light Chain test with Kappa/Lambda ratiodetects both bound and free light chains in serum. It is used to monitor patients whose free light does not show in serum or urine.The Kappa and Lambda Light Chain, Free, testdetects and quantitates free immunoglobulin light chains, without interference by whole immunoglobulin molecules.
There is an electircal switch that 'senses' when the emergency brake lever is applied and lights a warning light on the dashboard to keep you from driving in this condition. This switch may be faulty or out of adjustment, causing the warning light on the dashboard to turn on.
The light next to the battery warning light is the fuel injection system warning light. If it comes on and goes off after a short while it should be ok but if it stays on for longer than 5-10 minutes then get it checked out.
Check engine lights are designed to give a driver warning of a mechanical issue concerning the car. In a 1991 Chevrolet Corsica, if the light comes on while driving after 10 minutes on the highway, it is best to limit driving to prevent further damage. Check the owner manual for reasons the light may be coming on or let a mechanic evaluate the issue.
The overdrive warning light might start flickering when you are driving because of low transmission fluid. This light could also come on because of tension on the transmission while you are towing a boat or trailer.
