I have an 03 Tahoe 4.8 liter I'm getting OBD codes p0120 p0220 p 1516 p2135 please clean the throttle body replace the throttle body with the position sensor my car will not start


code p 0120 refers to mass air flow(MAF) sensor/volume air flow(VAF) sensor---low input===causes wiring short to ground ---MAF/VAF sensor---ECM
code p 0220 refers to throttle position sensor (TP) B /accelerator pedal position (APP) switch B--circuit malfunction===causes --wiring--TP/APP switch---ECM
code p 2135 refers to the same as p 0220 causes and sensors

I have p 1121 and a P 0401 codes on my 1998 ford windstar. are these related? what can I check? replaced the mass airflow sensor recently.




P1121 Ford Throttle Position Sensor Inconsistent with Mass Air Flow Sensor
http://engine-codes.com/p0401_ford.html no they are not related !
Are there any cracks in the rubber hose from air cleaner to throttle body ! That could cause the P1121 air entering after mass air flow sensor !
P1121 - Throttle Position (TP) Sensor Inconsistent with MAF Sensor The PCM monitors a vehicle operation rationality check by comparing sensed throttle position to mass air flow readings. If during key ON engine running self-test the comparison of the TP sensor and MAF sensor readings are not consistent with calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
  • Air leak between MAF sensor and throttle body
  • TP sensor not seated properly
  • Damaged TP sensor
  • Damaged MAF sensor
Drive vehicle and exercise throttle and TP sensor in all gears. A TP PID (TP V PID) less than 4.82 % (0.24 volt) with a LOAD PID greater than 55% or a TP V PID greater than 49.05% (2.44 volts) with a LOAD PID less than 30% indicates a hard fault. P0401 - EGR Flow Insufficient Detected The EGR system is monitored during steady state driving conditions while the EGR is commanded on. The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum.
  • Vacuum supply
  • EGR valve stuck closed
  • EGR valve leaks vacuum
  • EGR flow path restricted
  • EGRVR circuit shorted to PWR
  • VREF open to D.P.F. EGR sensor
  • D.P.F. EGR sensor downstream hose off or plugged
  • EGRVR circuit open to PCM
  • VPWR open to EGRVR solenoid
  • D.P.F. EGR sensor hoses both off
  • D.P.F. EGR sensor hoses reversed
  • Damaged EGR orifice tube
  • Damaged EGRVR solenoid
  • Damaged PCM
Perform KOER self-test and look for DTC P1408 as an indication of a hard fault. If P1408 is not present, look for contamination, restrictions, leaks, and intermittents

My 94 jeep wrangler sport 2.5L has been idling very high. I've changed the throttle position sensor, coolant sensor, control valve, replaced the vacuum lines and elbows, throttle gasket and reset it...


High idle could also be of air going in past the MAF mass air flow, just like a vacume leak. Tap the IAC idle air control valve and see if any changes? I normally like to spray water all around the engine specially the vacume pipes and the intake to find leaks (that was old school) now we have smoke machine which is accurate and detects a very small crack.

I have an '02 VW Cabrio that is giving me random 171 and occasional 102 OBD codes. I looked for and found a split hose near the air filter housing and replaced. I've not found any others with...


1st have you replaced the O2 sensor? Here is the technical stuff about this fault code
OBD 2 fault code P0171 VOLKSWAGEN - Fuel control System To lean engine cylinder bank number #1.
Possible causes:
Possible causes- Intake air leaks, spray propane around the intake manifold gasket and all vacuum connections and listen for a change in the engine idle speeds, any change indicates a leak.
- Faulty front heated oxygen sensor (a common cause if the car has over 50,000 miles on it)
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure Hook up a fuel gauge and make sure the fuel pressure is good/in specs under a load.
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

My Toyota 1995 22re ides but stalls when pushing on the gas pedal


I would check out the Mass Air Flow sensor and the Throttle Position Sensor.
The Throttle Position Sensor tells the computer what position your have on the throttle while your are pushing on the gas pedal.
The Mass Air Flow sensor tell the computer how much air is going into the engine at different RPMs.


A repair manual will show you how to check the sensors if they are bad. Auto-parts store will carry these books. It's about $20.

1991 toyota pickup dies when you release the gas pedal


There are couple of things I would check out that would cause this problem.

1. The Mass Air Flow Sensor. It measures how much air is going into the engine. Should be located on top of air filter box.

2. The air tube that goes from the Mass Air Flow Sensor to the throttle body. Check for leaks that would bypass air from going through the Mass Air Flow Sensor.

3. The Throttle Position Sensor. Located on the throttle body. This tells the computer what position the butterfly plate is on the throttle body. You control this plate with the gas pedal..

Issue with throttle control on my 2003 Maxima


I discovered that its the throttle body sensor. Its not sensing the postion of the foot pedal. The throttle body has a sensor that is linked to your gas pedal via a cable. The spring that the repair man mentioned could be the issue. The sensor then communicates to the computer the position and then computer then applies fuel, the mass air sensor then will communicate to the computer and the computer will then allow more or less air to fuel ratio. So if your stomping on the gas and there is not any response, then your throttle body sensor is most likely going out.
