6.2 Engine Light
Ive been driving with my engine light on in my 93 6.2 for a year and it would come on an off. Now i got keen and read my codes with the paper clip trick and found I have a 15(Coolant temp sensor circuit), 32(EGR circuit), and 33, Mass Air Flow Circuit is high)
Now my coolant light also comes on from times to time shortly after i had a starter and glow plugs done. Are these simple fixes? Should I just bring them into a shop? Has anyone had similar issues. The truck runs great I am just annoyed with the light show on the dash. |
These have unique code descriptions and the code #'s have different meanings from the gassers.
DTC 15 - Engine Coolant Temperature (ECT) Sensor Circuit High (Low Temp) DTC 32 - EGR Circuit Error DTC 33 - EGR Control Pressure/Baro Sensor Circuit High Sounds like a broken/bad ground wire/connection? Check ECM grounds for clean and secure contact-passenger side rear of intake. |
I installed a new Coolant temp sensor and my code 15, and 32 went away. Now its a code 33.
