Is the throttle plate closed all the way? The 4v wide open is a little low and the .6 closed maybe a little high. The wide open should be 4.5 -5 v. Are you reading 5v at the tps plug with the plug unplugged from the tps? Pretty much , what is going in should be close to what wide open should be.

I keep getting all these cods p0102 p1120 p1220 p1221 p1514 p1516 p0102 p1120


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

Is there a "computer flash update" for my 2001 isuzu rodeo ls 3.2l (v-6)


code p1120 refers tothrottle position sensor1--circuit malfunction---causes ---wiring open cuircuit--/short circuit to ground/short circuit to positive---throttlecontrol unit---ECM
code p0401 refers to exhaust gas recirculation(EGR) valve system---insufficient flow detected. ---causes hose leak/blockage--basic setting not carried out (if applicable)---wiring---EGR valve---EGR solenoid----ECM. I would replace the EGR valve for starters Get unit from the wreckers. You may have to have the CPu reset with a code reader tool

2004 holden rodeo 3L ITD. dt P1120. Saying tps fault. Used scan tool to inspect data list an ECU is recieving signal perfect. Goes from 16% to 100%. Double checked TPS output from TPS plug and goes from 0.6v to 4v nice an smoothly. Im suspect on ECU because when i erased code and started engine it revved up to red line by itself but only did once. Any help would be great....

I have a 2000 focus with a p1120 code what can I do to start this repair.


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.

I have a 1996 Mercury Grand Marquis, that had the check engine light come on last night. I stopped, and had a auto store check for the code, and it showed a code of P1120. They could not tell me what this...


The code indicates P1120 TPS Out Of Range Low according to the ODB 2 chart. Get a Haynes or Chilton's manual to get instructions on how to make this repair.

Frod 1998 explorer check engine lite come on says p1120 i change throtle position sensor but nothing happen .now p 1120 codes comes on .wen start in morning but it shut down


THIS CODE DOESN'T MEAN THE TPS IS THE PROBLEM, ALTHOUGH THE SWITCH MANY TIMES IS, THE CODE MEANS THAT THE CIRCUIT HAS A PROBLEM, THIS CAN BE THE ACTUAL SWITCH OR THE CIONNECTOR TO THE SWITCH OR THE WIRING TO THE SWITCH AND ALSO THE COMPUTER, IT TAKES A SCANNER WITH LIVE DATA FUNCTION TO LOOK AT THE SIGNAL AND DECIDE WHERE THE PROBLEM IS.

2000 VW Golf trouble code P1120


It can mean some points which can be faulty. It can mean that the ECU is totally failed or there us a serious electric failure. And thirdly, the most common thing that can happen is the Throttle Position Sensor which is also called TPS is defective, broken or out of range.
Please check the Car and call a technician who has mastery in repair because this code is serious.
Thank you Sir, Have a nice day.
