It sure will if it's bad.
It probably is something in the emissions. O2 sensor what year and make
When it's dead, check for spark & fuel to give you direction. Whichever one is missing you can narrow it down from there.
could be anything from a crankshaft sensor to a fuel flow sensor if you take it to a garage they will diagnose it and can reset it but can cost anything upto £50.00 to reset depending on where you take it
you can't. you need to fix what is causing the fuel vapor leak.
if its what I'm thinking of it determines the air and fuel mixture needed to keep the car running.
No, not and keep all your equipment the same. The crank sensor determines spark and fuel injector timing along with the cam sensor.
Modern electronically controlled engines use a sensor to keep track of the position of the pistons for spark timing. Since all the moving parts in the engine are mechaically linked, only one sesor anywhere in the system can provide the required information. Most systems put this sensor on the crankshaft. But a sensor on the camshaft would also work. The sensor itself is a simple magnet and pickup coil. The coil sends out a pulse every time the magnet passes it.
Pumps fuel to keep fuel supply coming once you turn the key on
The fuel pump usually is either always on or on based on demand pressure/vacuum. A bad crank sensor (one that tells the fuel system the engine isn't turning when it really is) will prevent fuel being introduced into the cylinders just like a bad fuel pump though. Really dumb design in my view-- my daughters VW Beattle was famous for these kinds of failures.AnswerYes
The oxygen sensor measures the amount of or lack of oxygen in the burnt exhaust exiting the engine in the exhaust pipe. It will then send a voltage signal to the vehicle computer. The computer uses that signal to control the fuel metering coming into the engine to try and keep the air/fuel ratio at 14.7 parts air to 1 part fuel. This is for emissions and economy reasons.
Inside the timing chain cover there is a crank position sprocket and a sensor that connects into the side of the timing chain cover. There is also a sensor in the distributor(this is the camshaft position sensor). The connector faces the firewall. To setup your timing you have to rotate the distributor to 0 deg or you will get a P1345 code. A timing light won't help. If you don't have the right equipment you need to take it to the dealer or keep adjusting the distributor until the code goes away. Jon
