2003 engine light, diagnostic mode?

Had this vehicle for 2 months, and now the engine light has come on. Don't know how to get into diagnostic mode, or even the reset procedure if the immobilizer gets activated. (only have the chip key, I have never started the vehicle with a non-chip key). I didn't get the owners manual either.

    is there another way? Chrysler minivans could turn key on-off-on-off-on and count engine light flashes...is there something like that on these vehicles?

Easiest way to fix it is go to a garage and have the diagnostic scanner hooked up to see what codes are coming up. Without doing this, it's almost impossable to find out which sensor is bad. There are so many sensors , also after the bad sensor is replaced, the mechanic can rest and clear the codes via the scanner.

To find out what the code is and/or erase codes you need an obd2 code reader. you can pick one up at any autoparts store,. and ur uplink should be under the dash

    i dont know about that but as far as the immobilizer goes, the obd2 reader should reset the computer for that as well. or the dealer can do it but i think it would cost around 50 dollars

2003 4500. Why have gauges stopped working?


You could have anyone of a number of different problems . I know your year vehicle falls in the range of GM instrument culster problems . There are little stepper motors ( electric motors ) that make the gauges move . There could be DTC'S - diagnostic trouble codes stored in the instrument cluster . An you have to know how the instrument cluster knows how much to move the needles on the gauges . All the input sensors to the PCM/ECM - engine computer vehicle speed sensor , fuel pressure , oil pressure , etc... All the modules on the truck are hooked together on a serial data communication network .The PCM/ECM sends this information out on the data bus for the other moduels that need the info .
Engine Oil Pressure (EOP) Gage
The IPC displays the engine oil pressure on the analog EOP gage as determined by the PCM. The PCM monitors the signal circuit of the EOP sensor. When the EOP sensor resistance is high, the engine oil pressure is high. When the EOP sensor resistance is low, the engine oil pressure is low. The IPC receives a class 2 message from the PCM indicating the engine oil pressure. The EOP gage defaults to 0 kPa (0 psi) when the following conditions occur:
• The PCM detects a malfunction in the engine oil pressure sensor signal circuit. Refer to Diagnostic System Check - Instrument Cluster .
• The IPC detects a loss of class 2 communication with the PCM.
Speedometer
The IPC displays the vehicle speed on the analog speedometer based on the vehicle speed signal from the PCM. The PCM converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed.
The powertrain control module (PCM) creates the vehicle speed signal by pulsing the signal circuit to ground at a rate of 4K PPM. The instrument panel cluster (IPC) converts the 4K PPM signal to a speedometer position. The IPC also receives a class 2 message from the PCM indicating the vehicle speed. The IPC uses this class 2 message for diagnostic purposes.
There could be up to twenty different DTC'S stored ,here is an a for instance
--------------------------------------------------------------------------------
DTC B1365
The instrument panel cluster (IPC) uses the ignition 0 voltage circuit in order to supply voltage to various indicators and gages. The IPC also receives a class 2 message from the serial data gateway module (SDGM) indicating the current power mode. Your best bet would be to take your vehicle to the Dealer or an ASE certified independant repair shop .

2003 Chevy Trailblazer engine power lose light come on


Hi Steve , your vehicle has electronic throttle control . I don't know if you are aware of this. The gas pedal have position sensors an a wiring connector with 4-6 wires .these wires are connected to the engine computer . an there is a electric motor on the throttle body assembly , the computer opens an closes the throttle . You probably have codes stored in the engine computer .
Reduced Engine Power Mode When the PCM detects a condition with the TAC system the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Acceleration limiting--The control module will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.

?€¢
Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.

?€¢
Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.

?€¢
Forced idle mode--The control module will perform the following actions:

-
Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.

-
Ignore accelerator pedal input.

?€¢
Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.

I have a 1992 Plymouth Grand Voyager with the 3.3L V6. The 'MAINT REQD' light has been on for months. I can't get the ignition cycling to give me a code readout. I don't if I'm doing...


When the Check Engine Soon Light comes on , your first instinct is to pull over and check out the situation. This is not necessary. This is the vehicles way of letting you know at its earliest stage that an error has occurred. No need to panic. If you have been driving with that all annoying light on, remember this : Your gas mileage will improve if the necessary repairs are made.
LOOKING FOR CODE INFORMATION GO HERE : DIAGNOSTIC TROUBLE CODES




The first thing to do when your "Check Engine Soon" light comes on is to determine the immediate cause. Consider if the vehicle is still performing as usual or if a loss of performance is noticeable. Generally a constant illuminated light without loss of performance points to an emissions related issue( this won't leave you stranded). When the light flashes, this indicates a serious engine failure condition and will require immediate attention. You may wish to take your vehicle to a local shop and have Computer Diagnostics performed. Usually costs under $100.00.


Generally all vehicles from 1996 and up have an OBD II computer. The Major problem when it comes to OBD II is that you can no longer acquire the trouble codes by counting the flashes of the Check Engine light like you could on earlier OBD I vehicles. You can take your car into a local high-tech service shop, where the minimum charge for computer diagnostics and engine diagnostics might cost you somewhere into three digits. Or you may want to learn about OBD II systems. in order to do so you will need an OBD II scan tool. I have already done the research for you and located several different scan tools for you to choose from. If you already have the code and need to know what it means check out our complete list of OBD II Codes Here.





OBD II scan tools connect to the vehicle's computer through a connector under the dash by the steering wheel.

Amber check engine light on a 2003 chevy 2500.


This means your vehicle has failed to complete one or more of a series of self-diagnostic tests, usually but not always emissions related. The only way to find out which system has failed the test is to have the Diagnostic Trouble Codes read with special diagnostic equipment. Once you know the codes stored in your vehicle's computer, it will help determine what repairs are needed.

Im buying a 1986 bmw 325e and it has a check engine light im familiar with locations and diagnostics of obd 1 and 2 vehicles but im not sure how and where to pull codes off of this vehicle is there a plug...


You can get hte codes from this BMW by turning the ignition key to the run position and then press the accelerator pedal to the floor 5 times, it will enter the diagnostic mode, count the flashes just like obd 1. Hope this helps, let me know

Air bag light stays on in my 2004 hyundai tiburon


Whenever the 'CHECK ENGINE' (Service Engine Soon) light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.
You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE the problem and perhaps eventually fix the problem.
Go to www.hmaservice.com and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.
