Will a bad O2 sensor or Tps throttle switch prevent a car from starting?

Although maybe possible, most likely not probable. Symptoms of a bad tps include rough idling, fuel-rich signs such as fouled spark plugs, black smoke ROM the exhaust, etc. I have never seen a case where the symptoms were ignored to the point where the vehicle would not start.

∙ 11y agoNo it will not. As a matter of fact, the O2 sensor is actually being ignored when you start the car, until it goes into closed loop mode.
O2, no. TPS, possible.

Wiki User
∙ 12y agoNo, it will run poorly but it will start and run.
Wiki User
∙ 12y agoPossible, but not likely.
Possible, but not likely.
Wiki User
∙ 11y agoYes, that is one of many things that can cause it not to start.

Is there a switch on the clutch that could prevent a car from starting?
yes, it is a neutral safety switch. When this switch has an open circut, it will not let the car start. The switch should be located under the dash on the top to the cluch pedal.
What does the manual lever position sensor do?
Is the device you are calling the manuall shift lever sensor really a neutral safety switch? It is a device to help prevent the vehicle from being startted in a drive gear.
Hi there you have a 1999 dodge ram diesel with bad tps throttle position sensor code p0123 I've replaced it but still when you push the throttle?
the code P0123 means, Throttle Position Sensor/Switch A Circuit High Input. sounds like a wiring problem to me. I had the same problem with a 99 Toyota tocoma when i replaced it i had to reset the CPU. On a dodge you should be able to disconnect both batteries for 15 mins to 1 hour and it mite reset.
What is the drawing symbol for a moisture sensor?
Same as a switch
98 Camry ignition removal?
The process of removing a 1998 Toyota Camry ignition switch requires taking apart the steering column and lower dash, as well as several of the under-dash relays. The ignition switch is connected to the key cylinder and cabin wire harness. A faulty ignition switch will prevent the car from starting.
What is the difference between a throttle position sensor and a throttle position switch?
A TPS is a variable resistor that tells the engine computer the absolute throttle opening percentage. A switch tells the system when the throttle is wide open for enrichment purposes.
Where is the Throttle sensor on a 2001 Dodge Caravan?
The TPS (throttle position switch) is attached directly accross from where the throttle cable attaches to the throttle body. It is held on with 2 torx type screws.
Can anyone tell you why you may briefly get a check engine light when starting up The computer code says throttle positon switch but this has now been changed and it still does it?
I had the same problem, so I changed the throttle position sensor and the camshaft sensor as well...it worked for me, hope it works for you too. also change the map sensor that was the reason the light was on
What are common fixes to a po121 code on a 2001 jeep Cherokee?
P0121 - Throttle Pedal Sensor Switch "A" Circuit Range/Performance. Most common fix is to replace the Throttle position sensor.
Can you show a picture where the throttle positions sensor switch it on a jeep liberty located?
No, I cannot show a picture.
What should you do if you have trouble code P2125 for your 2003 Hyundai Santa Fe?
Trouble code P2125 means: Throttle/Pedal Position Sensor/Switch ""E"" Circuit I would replace the throttle position sensor
Why is there no throttle response when the check engine light comes on?
My friend is having the same problem. After some research, I've come down to it being related to the idle switch on the pedal assembly. The switch is there because your throttle is electronically controlled and the switch is a canceller. If you release the throttle but the throttle position sensor is messed up and saying that there is a throttle input the truck will try to keep revving. So the idle switch cancels any signal that is being put out by the throttle position sensor. If the Idle switch sticks, it will cancel out your input into the throttle pedal. So when you want to go, the idle switch thinks that your still in idle mode. In a nut shell, people are saying that you need to replace the throttle pedal assembly. It's relatively easy, kind of expensive though. About $220.
Why are you having starting problems with your 97 sunfire they said it was a throttle positioning sensor but you fixed it and still didn't work?
I read somewhere on the internet that there was a defect with the ingnition switch due to a recall and what they were doing was installing a relay switch. i dont know if that is it but that is what i read and heard.
What does code p0121 mean?
code po121 means Throttle Position Sensor/Switch A Circuit Range/Performance Problem . it is usually indicative of a faulty throttle position sensor or faulty wiring harness in the engine bay.
Where is throttle position sensor on clio 1.2 16v 2001?
hi i have a clio 1.2 2001 and have a fault code p0225 throttle/ pedal position sensor switch c circuit. i have changed the throttle pedel and has made no diffrence the vehicle still wont rev up but cant find the throttle position sensor under the bonnet please can you tell me were it is located. thank you.
Where is throttle pedal position switch b on your 2000 Saturn sl 2?
The throttle position sensor is on the throttle body. That's the part of the engine that controls the amount of air allowed into the engine. To find the throttle body, follow the air intake routing toward the engine. The throttle body is the part that sits on the intake manifold. To find the throttle position sensor, follow the throttle cable to the throttle body. If it helps, have someone press down and release the throttle pedal while you're looking for the throttle body/position sensor. The throttle cable causes a shaft to turn, that's the part that controls the air coming into the engine. The throttle position sensor is connected to that shaft.
Will brake switch control prevent a car from starting?
Not to my knowledge.
