What kind of trouble code does a 1995 car have?
Vehicles older than 1995 models typically feature the OBD-1 trouble-code system; cars made after 1995 usually have the OBD-2 system.
How to retrieve car trouble codes with no equipment?
If the link has 12 ports rather than 16, connect ports “A” and “B” with a paper clip or jumper wire. Watch the “Check Engine” light for codes as documented previously.
Why does my car scan show no codes?
The scanner showed no codes, and said the car passed the scan test. I was expecting a sensor code, a fuel pressure code or an ignition coil code. The car had done this once before – but the code reader had correctly shown a faulty crank sensor.
What is the most common car diagnostic code?
CODES: PO171-P0175. One of the most common car problems involves a faulty oxygen sensor. A vehicle’s oxygen sensor monitors the amount of oxygen in the exhaust so the engine computer can adjust the fuel mixture to maximize fuel economy and minimize emissions.
What does it mean when your car has an error code?
It also contains a neutral safety switch, which ensures that you can only start your car in neutral or park. This code could indicate corrosion or other problems in the transmission range sensor.

What is the code for the Check Engine light?
Again, this is an informational code. With most vehicles, the TCM is the only computer that can turn on the check engine light. If there’s a problem preventing the light from coming on, you’ll see this code. The transmission range sensor tells the TCM the position of the gear lever.

Can a check engine light code be troublesome?
Oxygen Sensors, otherwise referred to as O2 Sensors, and their related check engine light codes, can be troublesome at the very best! Today we discuss the design and function of these sensors, and some of the pitfalls encountered during the diagnosis of their related fault codes.
What’s the best way to read diagnostic codes?
The Black Jumper wire in combination with the loose terminals shown above is really useful for grounding terminals of vehicle diagnostic connectors, to output the codes. One of their main advantages is that they provide a stable ground, to ensure the vehicle stays in diagnostic mode to display the codes while you read them.
