Can a upstream O2 sensor cause misfiring and engine hesitation at low speeds?
Todd63
what could cause a car to run for 20 minutes and dye and waiting about 5 minutes it will start back up and run for a couple of minutes and then have to wait and it will start back up and go for about 5 minutes and dye again. Chevy cavalier 2004

Can you show me a diagram of the upstream oxygen sensor?
Can you show me a diagram of the upstream oxygen sensor on a 3.5l liter Oldsmobile Intrigue engine?
Where is 02 sensor on 1996 ford explore upstream?
They should be in the exhaust system close to the engine ( either in the exhaust manifold outlets or the exhaust pipe ) before the exhaust enters the catalytic converters Bank 1 is the passenger side of the engine and sensor 1 is the upstream sensor Bank 2 is the driver side of the engine and sensor 1 is the upstream sensor on that side
What are the symptoms of a bad camshaft position sensor?
It is important to recognize when poor performance is due to a bad car part. Symptoms of a bad camshaft sensor are misfiring, hesitation during acceleration, and not starting.
What does o2 sensor upstream and downstream mean?
it refers to the location of the oxygen (o2) sensors relative to the engine. The upstream sensor is the one closest to the engine. The downstream sensor is furthest from the engine. Think of it as the way a stream of water, or in this case, a stream of exhaust flows.... From the engine To the tailpipe.
Why does a 1995 Pontiac Sunfire engine turn but wont start unless you floor the gas pedal?
Probably a leaky FPR diaphragm or bad MAP sensor reading. If bad FPR diaphragm replace the fuel pressure regulator. This will also fix the misfiring, excessive fuel consumption, catalytic converter burning up, and rapid engine wear. If MAP sensor, replace sensor and/or hose to sensor. May also fix: check engine light on, hesitation on acceleration.
Is bank1 sensor 1 and 2 are they both upstream?
No Bank 1 is the passenger side of the engine in your Ford Expedition , Bank 2 is the drivers side Sensor 1 for both sides of the engine are before the catalytic converters ( upstream ) Sensor 2 for both sides of the engine are after the catalytic converters ( downstream )
How is a crankshaft position sensor used to monitor misfiring?
by sensing engine RPM it can teel if engine is not running smooth by sensing the rotation of the rpm's of the engine.
Where is the 1 sensor 1 oxygen located on a ford E150 4.6 engine?
Bank 1 is the passenger side of the engine in your E-150 Sensor 1 is between the engine and the catalytic converter ( upstream sensor )
How do you tell if an oxygen sensor is upstream or downstream on a '96 Geo metro I just have one.?
The closer to th engine is upstream and the farther is downstream Before the cat upstream After the cat downstream.
Where is o2 sensor code 1151 upstream bank 2?
bank 2 is the drivers side of the engine on your Ford Expedition sensor 1 is in the exhaust upstream ( before the exhaust enters the catalytic converter )
How do you know which oxygen sensor is bad in a 2002 Dodge Caravan?
Get the check engine light looked at, the code will specify if it is the upstream or downstream sensor. The upstream will be on the exhaust manifold, and the downstream will be on the pipe after the catalytic converter.
What montiors the engine for a misfiring engine?
if you mean that the distributor is not firing right, then there is a sensor on the back of your distributor (depending on your car year, but most likely) if you mean the timing is off, then the knock sensor i guess
