If your car isn't experiencing emission-related problems you don't need to have a code read, though it could be useful to have a scan with a laptop with rather better software than to be found in cheap hand-held code readers. Such scanning software will report pending faults so repairs or rectification can be carried out before they become a problem.

A code read is only the second step in fault finding an emission-related problem. The first step is to ensure the maintenance is up to date and properly carried out and a thorough visual inspection of the underbonnet area.
After the code read it is as well to verify the results by examining live data or testing the "guilty" sensor independently, though if it is a really inexpensive type it is sometimes as well just to replace it.

It isn't unusual for trouble codes to be misleading or even wrong and even when a code proves to be right the code cannot tell you whether it is the sensor, the wiring or connectors or the ECU that is at fault. It takes skill and experience to interpret the results of both the code read and further testing. Lots of people have spent great amounts of money on unnecessary new parts because they have neither.

2000 Subaru Impreza Outback Sport Wagon. Check Engine Light on. PO141 fault code: "Rear Oxygen Sensor Heater Circuit Malfunction".


This is almost always a failed heater circuit in the O2 sensor. Replace the sensor, clear the code. If the code comes back, we'll know it has a vehicle wiring problem. It is helpful to know that this sensor performs no important function. You could cut it from the vehicle and it would not effect performance or operation in any way at all. This sensor is only there to determine if the catalyst is work and doesn't affect engine operation. The sensor only operates when hot and since it takes longer to heat up on its' own, it has an electrical heater to help it operate faster. It is one of those things that you have to determine if the expense of repair is worth not looking at the 'check engine' light since it has no bearing on the safe operation of the vehicle.

Engine dies while driving can usually be restarted.


Whom ever replaced the sensor, must have
done so, based on the code & not on testing
to find out why the code was set.
Codes do not tell you what is wrong or to replace
any parts.
My advice would be to find a shop that is the best around
at diagnosing vehicles,I wish I could give you a guide &
questions to ask in your search but I can't
You will have to ask other people where they go to
& what type issues they had & the shops can resolve.
On a vehicle 10 years old & for those who never change their
oil on a new vehicle & that includes most people,you could have
mechanical problems
A sensor reports an out of range condition,so if you have no
wiring issues or other sensors pulling that one down,mechanical
issues are a good place to look
The way to do that is using an oscilloscope & the proper
software,& not every shop has that-- shall we say equipment,
knowledge & skill level.
Use your codes & Google them & your vehicle & look for
known issues with whatever motor you have.

Service ride control chevrolet


Hi there:
You will need to have the system scanned for codes. Each shock has a sensor there is a ride height sensor as well. The computer will give a code which will show what is the cause. use a scan tool to access the suspension module to get trouble codes.

The service ride control is related to the level control air shocks in the rear of the vehicle. A scan tool pulling fault codes would help isolate the cause. It is almost always the exhaust solenoid in the pump assembly but it can be other issues. We would need to know a fault code to go further. I suggest to check this TSB from GM in THIS LINK

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Once cooling fan comes on it wont turn off until you turn key off


Hi and welcome to FixYa!

If that's the case then the problem can be on the cooling fan sensor. If the sensor is faulty issues like this occur. I strongly suggest that you have it replaced to resolve the problem.

Hope this helps and thank you for using FixYa! Have a good one!

Check engine lioght is on and d4 light is blinking n when u step on the gas on d4 it doesnt wanna go???? wats wrong wit it


There are many other things that cause the D4 to flash. The D4 light turning off is similar to the CEL turning on. Some codes cause the light to blink, some turn it off. There's an error code stored, pull it and start from there.

Check this DIY: Diagnosis: Pulling Codes

Definitely pull all the codes and let us know what you find. Once we know what the codes are then we can help you troubleshoot the issue/s. Alot owners talk about VSS (Vehicle Speed Sensor) but the VSS may or may not be part of the issue but per your description it may sound like a main relay to a tranny issue.

Keep us updated.

My girlfriend took the car to auto zone today and they listed three codes for the car, this one im not sure of, is a p1336. they told her that it has a missfire in bank 1, the o2 sensor is bad and one of...


P1336-crank or cam sensor
PO 141 & PO 171 are O2 Sensor Codes

All Auto Zone did, was confirm an issue with your
vehicle.
You don't know any more than when you went there

Find a good repair shop to diagnose your vehicles
problems.
You don't have all thoses parts failing and you replace
nothing without understanding the vehicles systems
and testing to determine if you even need parts to resolve

We could use a vehicle discription in the future

Erratic speedometer causing miss shifting. Seems to only happen with Security codes or possibly other engine codes as well. the latest issue im haveing seems to be security of some kind.maybe a bad chip in...


Propably the VSS - vehicle speed sensor . The PCM uses this input to control shifting an speedometer information . Or a wiring issue . If you think there are othe codes stored in the computer the wise thing to do would be to have read or pull . You don't say what engine size yours is ? 3.1 L or the 3.8 L ? How many key's do you have on your car key ring ? Have other car key's ? confusing the control module . Speedometer
The IPC displays the vehicle speed based on the information 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 (4000 pulses/mile) from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 mph (0 km/h) if a malfunction in the vehicle speed signal circuit (4000 pulses/mile) exists.

Air bag light stays on in 1997 ford f-150


HI. This will essentially be an indication of SRS(air bag) module failure ,or an individual crash sensor may be malfunctioning. These sensors are locate all around the vehicle. You will need have the codes pulled by a certified ford code scanner tool to actually isolate the culprit. With that said; it will most likely be an issue that will concern one or more of the crash sensor mounted throughout the vehicle.

  • Worst case scenario will be total SRS module failure, which will require you to have the entire module replaced.
