I am getting a trouble code P0226 throttle/pedal position sensor/switch c circuit range/performance. The error comes back when I delete it.
I have recently replaced the gas pedal so that should not be a problem.
What should I check/repair/replace?
 
Conflicting information don't know which is right. This point to the throttle body.

OBD2 Code P0226 Fiat definition:
Electric Throttle Control Actuator consists of throttle control motor, throttle position (TP)sensor, etc. The throttle position sensor responds to the throttle valve movement. The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
Symptoms
Possible sumptoms of OBD code P0226 Fiat
– Engine Light ON (or Service Engine Soon Warning Light) – No throttle response
Causes
Possible causes of OBD code P0226 Fiat
– Harness or connector (The TP sensor circuit is open or shorted.) – Electric Throttle Control Actuator (or Throttle Body Motor) – Accelerator Pedal Position Sensor (APP) The Error code is generally activated on detection of the following conditions: An out of range voltage from the Accelerator Pedal Position Sensor (APP) sensor 1 is sent to ECM.

Thanks. I will check the harness and connectors on the throttle body. Do you happen to know the fiat oem number for a new throttle sensor? It's a panda 1.3 2009. I tried fiat Denmark and they couldn't help me
 
I changed the gas pedal + sensor less than 6 months ago, so it shouldn't be the problem. Spoke to Fiat Denmark, and they told me there is no throttle body sensor, so that cannot be the problem neither.

The 1.2 has on in the body and if it read different to the peddle one it will throw up an error

Clean of the body might be in order first in case it just jamming.
 
Its a 1.3

It still has electrical connections on the throttle body


I am guess it will still throw the same error code if its butterfly plate is at a different angle than expected.

I'm a bit confused. Is there a throttle body in the engine bay, og do you mean the gas pedal?
Fiat told me there is no throttle body / throttle position sensor in the engine bay.
 
If it's a diesel, it's not a throttle body, its a shut-off butterfly valve that is used to stop the engine running on due to residual fuel (or oil/egr deposits) when turned off.
The "throttle" pedal on the diesel just provides signals to the ECU that are proportional to pedal position. There are two signals for safety. If these are different it will produce an error. It's possible that the new sensor as not installed / set-up correctly or could be faulty.
What are you using to read the code? If it's a generic reader the code descriptions can be misleading. Restting the self learnt functions on the ECU may help. Using Multiecuscan or similar Fiat specific software to look at the pedal sensor votages would be a good next move. Other possible faults are bad connection, intermittent short to ground or possibly an ECU fault.

Ahh, that makes sense. I use one of those cheap ebay elm things. So not the most accurate thing. I will try Multiecuscan next time it gives me an error.

Isn't it a Diesel Pre–flap ?

Doesn't it need to know what angle its at ?

Doesn't a direct injection stop when the injectors stop ?

As it a generic code for both petrol and diesel cars

Throttle position or pedal position

I am guessing the pre-flap out of position will throw the same code. But I could be wrong

I don't know for the Panda 1.3 engine, it's not on the 1.9 16V. In either case it's not a throttle

May be, maybe not, but probably not. It's not a critical control so may not be servo controlled at all. The EGR valve typically has no position feedback but it can vary. No position information needed if it's just open/close.

In theory, yes, but if there is any leakage it will run on. Older diesels had a fuel shut off valve. A diesel can also run on slightly from EGR deposits.

I think it's just throttle (pedal) position error, but that's the trouble with generic code readers, get Multiecuscan

Just asking if this was ever solved as now my panda 1.3 multijet is showing same fault code.When braking engine slightly revs lower then higher likes it's trying to stall then after around 6-10 miles warning light comes on with this fault code?

Where is the throttle body & how easy is it to get to so I can clean it if it is this?

Hi, if you read the original thread you will see that diesel engines do not have throttle bodies so no one can tell you were it is. If you want to know the outcome of the original issue addressing the original poster kieler would be better than just quoting yourself.

hi, on starting my 55 panda mj ,( unused for a couple of weeks ) i revved it up to 3,8oo rpm a couple of times. eml light came on dash. i plugged in a multiscan ms300 & it showed code po226 . ? any ideas. cheers, steve.
