Don't know what kind of code reader your friend used but that is a bogus coded . I work at chevy dealer ,have factory service info . Code's on all vehicle are P , B, C an u codes . P - powertrain B - body control module , C - chassie , U - communication network .
Your best bet ,take it to a qualified repair shop.
engine was probably blown ?????? Engine light ? Check engine light bulb blown .
Go local Autozone and ask to read OBD error code for free.
or buy any cheap code reader/scanner for now and future use ($30 to $1000. $30 is enough)
It's called "OBD scanner" or "OBD code reader".
Other than that, nobody can tell you what was/is wrong with your car.
BTW, OBD error codes are different by manufacture and year/model.
after you buy code reader, google it with your year/make/model.
or Autozone reader may tell you in plain English (other than P0125, B0432, etc)
Import cars built prior to OBDII scanners are tough to diagnose. There should be a throttle position sensor that could be faulty, or you could have low fuel pressure. It takes alot of guessing or trial and error without a scanner and flow charts.
You can unhook the battery , wait 1/2 hour then hook it up again. Or get a code reader, see what the code is, then erase it with code reader, Auto parts store have cheap code readers, some will actually read it for you, then erase it if you like.
More important- you cant get an inspection sticker if u erase it. It will still show on computer. Find out what code it is giving and try to fix it
The codes should be cleared with a scanner. However, on a 1995 Aerostar, we are talking about an old EEC-IV system. You cannot clear codes on that vehicle with a generic OBD code reader because it is not OBD compatible. You need to get access to a Ford "Star Tester" or an aftermarket scanner that can emulate a star tester.
Codes can also be cleared on that system by disconnecting the negative battery cable, but this is NOT the recommended procedure because disconnecting and reconnecting the battery cable can cause voltage spikes that can damage sensitive computer equipment in your vehicle. If you decide to do it this way, make sure that you leave the battery disconnected for a minimum of 15 minutes before reconnecting the cable.
The service engine light should only come on when the PCM detects a fault in one or more of the systems it controls. It should also store codes.
If a simple code reader was hooked up to read the codes perhaps the code reader is only good for the generic codes and your PCM has model specific codes stored in it. Some code readers cannot read those codes. A shop scanner may be needed to get codes.
You need to have it hooked up to a scanner or a code reader at the very least to find out what codes you have. There are many causes that make the light come on and you can't tell what why without a scanner or code reader. Some part stores will plug in and read the codes for you. AAmco advertises that they will hook your car up to a scanner for free to retrieve codes for you.
Your Service Engine Soon light has nothing to do with reminding you to change your oil. The light is controlled by the ECM (Computer) in your vehicle. It monitors various sensors in your engine and compares them to variables or programs that is in its memory. When something is not registering correctly or is outside of its parameters it will turn on a MIL(Malfunction Indicator Light)or in your case a Service Engine Soon light. You will need a OBD II ( On Board Diagnostic) reader or scanner to hook up to your diagnostic port under your driver's side footwell to read what code the ECM is putting out. Than with the code the mechanic can look up the code to see what part is sending a malfunctioning. The scanner can also read and erase the code too. You can have your code pulled up with a OBD II scanner for free from any AutoZone store.
