Can a diagnostic connector on 1995 Toyota 4 runner be jumped over with jumper wire to get check engine codes?


There is probably a way to access codes by using a jumper and causing the engine checklight or an integral led to flash in groups. I can't say which pin or pins need jumping.

I suggest you ask the question of google and click on the youtube video.

All Toyota vehicles with electronic fuel injection utilize the Toyota EFI or TCCS engine management system. This system incorporates many features to enhance performance, emissions, and drivability. One feature is the Self Diagnostic System. The self diagnostic system monitors engine operations and when a particular sensor or input varies out of specified operating parmeters, the "Check Engine" will be illuminated.
READING THE TROUBLE CODES
Reading the diagnostic trouble codes is very easy. You will need a paper clip or auto wire to short the check connectors of the diagnostic connector. The diagnostic connector comes in two types. The early system is located on the inner-left fender well and is a round, green connector, usually located near the air cleaner. Simply jump the two terminals in this connector with the ignition switch in the "ON" position and the engine off. Later models, '87 and newer use a multiple terminal "DIAGNOSTIC" connector which is a small, rectangular-shaped grey "box", usually located near the right fender in the enigne compartment. To get codes out of this type of connector, jump the "TE1" and "E1" teminals. Finding these terminals is easy as the inside cover of the diagnostic connector contains a schematic of the connector pinouts. If the underhood emission decal (VECI) is still intact on your vehicle, the proper pins for this are outlined there as well.
The trouble codes will appear as flashes of the check engine lamp. Be sure the ignition key is on, the engine off, and your foot off of the accelerator when reading the codes. Two different codes may appear: One-digit and two digit. One digit codes have an approximate 4.5 second delay between flashes with the check engine light illuminating for about a half of a second. Mulitiple codes have a 2.5 second delay between them. For example a code two flashes the check engine lamp two times in a little over one second: I I. If two codes are stored, such as a code two and a code four, the lamp may flash as such: ....I I....I I I I. Crude examples but you get the idea. Two digit codes are similar but will flash the lamp with the first number first and the second number last. An example of a code twleve is I ....II and a code twenty four is I I..IIII.

Toyaota Camry 1994 engine won't start, Engine light on


I would check for fuel,(pressure and injector pulse), spark, and compression, before checking any codes. Lack of any of these basics can result in codes, and then you waste alot of time chasing a symptom, instead of the actual problem.If more people followed basic diagnostics, which always come back to these three basics, rather than chasing codes first,they would find no starts much more quickly.

I have been trying to retrive the DTC's from my 95 lumina. I tried the OBD-I process, but the MIL did not flash the codes. I bought an CAN OBD-I & II tool, but the reader tells me that the tool is not...


On some 1995 OBD 1 models with a 12-pin Data Link Connector, trouble codes can be accessed by connecting terminal B to terminal A with a jumper wire. With the key in on position, the codes can be read by watching the "service engine soon" light. HOWEVER, some models have a 16-pin DLC and you have to jump terminals 5 and 6 to get the trouble codes to flash.

Check engine light flash then steady


Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. If the light is flashing there is a severe failure of the emission-control system that is causing the engine to misfire to the point that the catalytic converter is damaged each time the Check Engine Light flashes. Even if you reset the light, if the underlying problem is not addressed it will come back on.

Engine light on 1994 toyota camry is on.


It has a trouble code, you need to have it scanned. The light will flash the trouble codes if you jump terminals E1 and TE1 in the diagnostic plug.

How to read trouble codes on 1998 Toyota Camry w/o scan tool


You can go to any auto parts store and they will usually read them for you for free. Around the late 90s many of the auto computer systems began requiring scan tools rather than the older method of simply flashing lights on the dash if you jumpered the correct pins.
