Default Car threw a code, now what. Help please :o

The check engine light just came on. I jumped the harness and it threw 7 long blinks. Searching HAN, it seems to be a problem with the automatic trans axle.

What should I do now?

Are there more detailed codes to be read? If so, will taking it to a place like Auto Zone or Kragen get that information? Thanks

Vato Zone, esse.
Pull the DTC code.

If D4 is blinking, theres a different service connector (under the driver's side kick panel) to pull error codes for the transmission.

If it isn't, scan from the OBD-2 port. It'll probably be P0122 or P0123, both of which indicate faults with the throttle position sensor.

Thanks. I just checked the D4. It is not blinking.

What does a TPS fix look like

If you don't have a short in the wiring, it's a remove-and-replace kind of job.
The sensor bolts to the throttle body and measures the position of the throttle (obviously).

It should read 5V+ with the throttle opened fully and about .5V+ at idle.
If you have (or can get) a 1997 DC4 Helms manual, check page 11-59 for the flowchart.

First things first, though. Confirm that you've got a P0122 or P0123 error.

What year car? I know on the later models, the TPS sensor is "not replaceable". The factory uses a stupid special kind of fastener to attach to the TB.

From the helms:

"Automatic Transmission malfunction with the automatic transmission controls"...doesn't sound like TPS to me. The TPS has its own code.

I think it's probably just a weird reading the ecu got from a sensor, so it tripped the code. Reset the ECU and see if it comes on again.

Code from CEL blinking > vato zone reader code

They told me a recent law was passed in CA. I dont know how true it was. But I got the code read, and I got:

0700 and 0740.

:thinking: I got the code cleared and so far the light is still off. I am going to see if it comes back on.
