My 2000 ford focus se read p1120. already replaced the throttle position sencer but still shows p1120 code

Timing, engine control module, throttle position sensor, air flow meter. Run a diagnostic test to see what codes it shows so you can determine the exact cause.

Sorry your rebuilt trans did not fix your problem P1120 is TPS out of range The throttle position sensor responds to the gas pedal movement . of speed and angle it is moved Most sensors are 3 wired which has a supplied voltage of 5 volts and a ground and a signal return voltage this signal starts around .5 volts closed throttle plate and slowly works to 5 volts at full open position with a volt meter test the return signal while operating the throttle plate (engine off key on) look for glitches is voltage span go slow if this test fine check at computer the wire can be broken somewhere.

clean your throttle body first you might need to get a new throttle position sensor

Hi Robert, It would help us to know which vehicle as the codes very well may be vehicle specific.Ford seem to have codes of that numerical range, so I'm assuming your vehicle is made by Ford.
P1120 refers to the Air flow sensor. P1120 the throttle position sensor. 1220 Series Throttle Control Fault (probably related to the TPS) 1221 Refers to the high speed fuel pump relay having been activated. 1516 Intake manifold runner input error. Cannot find P1514 Hope this is helpful. I suggest sorting out the air flow sensor and the throttle position sensor to begin with and that may sort out the other defects. Very often one sensor giving an error reading will trigger others. Regards John

Diagnostic Trouble Code (DTC) P1120 indicates that the Throttle Position Sensor (TPS) closed throttle position is below the range of 3.4 percent (0.17 volts). Possible causes for this DTC are:

· Damaged wiring harness or connectors

· Open or shorted Reference Voltage (VREF) circuit

· Faulty TPS

· Faulty Powertrain Control Module (PCM)

The methods/steps for diagnosing this code depend on how the code was stored and retrieved.

This code can be a Key On Engine Off (KOEO), Key On Engine Running (KOER), or a Continuous Memory code. To properly diagnose the cause of the problem a scanner must be obtained that has the ability to read each of these as well as the capability of reading live engine data from the PCM.

Direct voltage readings should be taken at the TPS connector and compared to the live data at the PCM. This will eliminate the possibility of a faulty PCM. The VREF and Signal Return circuits must be verified between the TPS and the PCM. Also the Sensor Ground circuit must be verified between the TPS connector and battery ground.

the throttle sensor is on the end of the throttle pedal ,and another motor on the inlet manifold where the butterfly is ,now iam not sure here as to what the significance is of sensor A is as to weither its
the engine side or the interior one on the throttle pedal .
P1120 Throttle Position Sensor A Out Of Range Low (Ratch too low)

i would check you mass air flow sensor i think you ll find your problem there
give me some feed back if this helps
good luck

A P1120 means a throttle position (TP) sensor out of range. It could be TP circuit with frayed wires, corrosion on TP circuit connectors, or TP sensor loose pins. If you are not knowledgable in this area, I highly recommend that a knowledgable mechanic deal with this issue and may recommend a replacement.

P1120 Throttle Position Sensor out of rangeMake sure the connector to the throttle position sensor is clean and tight, if it is replace the sensor, clear the code.
