What is the oBD code 133 on a ford ranger mean?
Trouble code P0133 means: O2 sensor circuit,slow response (bank 1,sensor 1)
How can you trace a vacuum leak on a 2001 Saturn sl?
The way I do this is old school.
Examine all vacum lines, conections, Ts lines and accessories.
Start car and listen, sit in drivers seat with door closed and listen with stereo and heater off, turn heat on fan on lowest setting, change to all heat cool and defrost, foot and AC outlet settings.
If by now you have not heard a hiss from a leak then the next step must be performed outdoors on a fairly wind calm day. Take a propane plumbers torch. Turn it on so it leaks propane with out lighting it. Move slowly past intake gaskets, vacume lines and accessories. The engine note will change for a split second.
Good Luck
How do you reset P0446 Error Code?
pull the battery for a few minutes. if it comes back check gas cap seal or purge solenoid temporary relief
What does the check engine light error code P01400 mean on a 1996 Ford Bronco?
did you mean code P0140 ? this means o2 sensor no activity( bank 1 sensor 2) in other words replace the O2 sensor. hope this answers your question.
The cost of this repair would be contained in the labor 'flat-rate manual' which is not available easily or readily available as a normal reference item. You should contact the dealer who analyzed the problem and ask them what THEIR charge would be, and then call around to several other independent, TRUSTED, repair shops and inquire.
What does error code -24 mean?
It depends what item is reporting the code?
Car
Computer
Software?
Be more specific
What does the code p1401 manufactured controlled auxiliary emissions control mean?
It depends on the make, but most likely a malfunction of the egr temperature sensor.
How do you fix diagnostic error code P0075 for a 2002 Ford Explorer?
Code 75 means BOO switch circuit closed,ECA input open
When the malfunction light along with electronic throttle control comes on what does that mean?
It means that the computer has detected a malfunction and set a code. You will need to have it checked with a scan tool to know possible causes.
What does a 324 error code mean?
it means that the server closed the connection without sending any data.
What does OBD2 code P1032 mean on a 1999 Volvo V70?
Trouble code P1032 means: HO2S heater warm-up control circuit (sensor 1 bank 1 & 2)
Ford has a big long list of things for a tech to accomplish this with a scan tool.
To do the same thing on your own As long as the car (Explorer in your case) works correct, otherwise you are going to need to pay Ford.
Let the car sit over night.
Key on and cold start without any delay and turn on head lights, rear window defrost, AC or Heater full blast. Allow to idle for two minutes.
Shut off all the accessories turned on and pull away at about half throttle if possible. after the first acceleration, use accessories as desired.
Go for a half hour combined drive through town and at least 15 minutes steady throttle highway speed.
Allow 2 minute idle before shut down.
This will hopefully get all the self check functions done and you will pass emissions testing.
Where is the obd port in a 2004 corolla?
The diagnostic connector is under the dash on the driver side.
What is obd code 37 for 1994 dodge ram 1500 5.2l engine?
Torque converter lock up solenoid circuit malfunction.
What does error code P0351 for 2000 Ford Explorer?
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD2 vehicle diagnostics. Although generic, the specific repair steps may vary depending on make/model. The COP (coil on plug) ignition system is what is used on most modern engines. There is an individual coil for each cylinder that is controlled by the PCM (powertrain control module). It eliminates the need for spark plug wires by putting the coil right above the sparkplug. Two wires are dedicated to each coil. One is a battery feed usually from the power distribution center. The other wire is the coil driver circuit from the PCM. The PCM grounds/ungrounds this circuit to activate or deactivate the coil.
Where is the code reader plug-in?
The OBDII port can always be found within a foot of the steering column usually at the bottom or under the dash.
HO2S Heater Control Circuit Low Bank 1 Sensor2
symptoms
Other than the MIL light illuminating you may not notice any performance issues.
cause
A short in the O2 sensor heater circuit or the sensor itself
A faulty O2 sensor heater
Wiring or connectors are broken or frayed to the sensor or relay
Bad PCM or ECM
The fix
Correct wiring short or loose connector found in inspection.
and/or
Replace the bank 1 sensor 2, O2 sensor
Replace PCM if circuit has failed and no wiring issues present, good O2 sensor
This code means that your catalytic converter efficiency has dropped below the nominal value. p0420 is a generic code for the catalyst to indicate that you need to investigate a potential problem with your emissions system associated with the catalytic converter.
Code P0420 means "Catalyst System Efficiency Below Threshold (Bank 1)"
P0420 is actually Catalyst System Efficiency Below Threshold Catalyst System Efficiency Below Threshold.
This means that the secondary O2 sensor detects that the catalytic converter isn't working as efficiently as it should.
This engine code can be triggered by any one of the following:
1.) The catalyst in the catalytic converter is cracked, clogged, or otherwise damaged.
2.) The secondary O2 sensor is malfunctioning.
3.) There is an exhaust leak.
4.) The computer unit is faulty.
Trouble code P0420 means: Catalyst Efficiency Below Normal (Bank 1)
Code PO420 is catalytic converter efficiency low bank 1, sensor1. You did not state as to the year,make and model of the car as well as the engine size. I am a member of IATN and the majority of there fixes was related to someone installing an AFTER MARKET converter. There is a big difference. I strongly suggest that you go to a repair shop with the proper equipment as well as a very good tech to diagnosis the problem. You could replace parts and never fix the problem.jd1709
What does the error code P701 mean on a 1998 ford ranger?
Trouble code P0701 means: Transmission control system,range or performance problem
What does fault code P1296 mean on a 1996 Chrysler Sebring convertible?
Trouble code P1296 means: No 5 volts to the MAP sensor
What does code P0125 mean on a 99 Lexus gs 300?
Trouble code P0125 means: Insufficient coolant temperature for closed loop fuel control
