If the fuel pressure regulator is no good it will casue fuel to go into the vaccum hose and into the manifold which will cause flooding, try and unplug the vaccum line from the fuel regulator and start the car if fuel comes out of the regulator will need to replace it.

Car won't flood because of the TPS. But it will if the "fuel pressure regulator" is out of range (vacuum line is off?). The TPS is part of the throttle body.

2007 Suzuki XL7 - Error code reads p0122 and the computer in the dash reads Engine Hot- A/C off. It turned over earlier but Car wont start now. Battery is new, all fluid levels ok. AND... can anyone tell...

id use no start rules, the TPS 122 may be wrong. (idle switch)
ever use a cheap scan tool?
did you remove the TPS or fiddle its screws?
yes it does have calibration, and is different for each generation of car.
use alldata dot com or mitchells online, its all there.
or get a ebay fsm for this exact car cheap and used.

no starts:
flooding or dry sparks?
besides the basics, 1: good compresion and good timing)?
do you have spark. at 4 spark plugs.?
are the sparks dry or fuel soaked ?
if no spark , trouble shoot that.
if no fuel at all, check fuel pressure.
if flooding, a long list. of checks.
if it fails to start due to loss of fuel , try test fuel.

Dumping too much fuel while running

Clearly some fancy diagnosis and testing is needed and checking the fuel pressure will be part of those checks as would testing the injector spray patterns.
If the injectors are producing droplets that are large or are dribbling or leaking the oxygen sensor will see the result as a lean mixture and increase the injector duty cycle making the situation intolerable at idle when the intake air speed is too low to break up large fuel droplets.

Just an idea...

I can't find the throttle position sensor on a 2004 suzuki Verona. I need to change it as the car keeps dieing at stop lights. Can you please reply back. your help would be greatly appreciated.

If you can't find it, then that means you haven't tested it. If you haven't tested it, then you can't possibly know for sure that it is what is causing your stalling problem.

The Throttle Position Sensor (TPS) is very UNLIKELY to cause your engine to stall at stops anyway. A more likely candidate would be the Idle Air Control. (IAC) You won't find an IAC for your vehicle at most aftermarket parts suppliers. You will most likely have to buy on from the dealer. (For example, AutoZone does not even list one for your vehicle.)

If you still think you want to waste your money on a TPS, it is located in the same place that it is located on ALL cars...On the side of the throttle body.

The overdrive kicks out intermittently with no perceivable reason on my 1992 Dodge ram Diesel.

Believe it or not the most likely cause is a weak battery or batterys, and/or dirty battery cables. It causes electrical noise in electrical system which affects the computer. Test each battery indepentantly and clean all of the battery cables and grounds and see if that helps.

I changed the fuel pump and fuel filter, im getting gas upto the injectors/carb, but only starts if i put gas in the carb, but then dies quickly wont get gas. any ideas?

If the tps (throttle position sensor) gives a high signal it will put the computer in clear flood mode which shuts off the fuel injector. Easy test, unplug the tps and try to start it. The tps is the 3 wire sensor at the end of the throttle plate If not suspect the ignition module under the distributor cap.

Code p0122 and p0123 after changing computer


The problem is regarding TPS (throttle position sensor located in throttle body). Both codes are TPS voltage out of range (low and high) If you get both codes at once, then :

TPS may be defective,
wiring to TPS may be shorted to ground.
There may be a problem in the +5V circuit powering the TPS.
There may be a problem with ECU connector.

2004 Alero fast idle code po123

This code means that the vehicles throttle position sensor has reported too high of a voltage. The three most common causes of this are a fault in the wiring in the tps circuit, a defective tps sensor, or a bad ecm. The first thing I would do is carefully inspect and test the wiring in the tps circuit. This more than likely will be the problem. If after doing this, you find no problems, then test the tps itself and proceed with further testing from there according to what the manufacturer advises in their testing procedures.

Flooding out

If you are sure it is flooding try a TPS throttle position sensor. It is located on top of the engine where the carburetors use to go. It is a small part, like a cigarette lighter and has 2 screws and 1 electric plug. Remove it and line up the slots on the replacement and it should work.
