Once again my 94 decided to throw some codes at me when i started it this morning.
Ran both tests and got the following codes
Engine on: 116, 538, 536
Engine off: 214, 543, 556
Alright i already looked them up so i know what they are for.
- 116 - Engine Coolant (ECT) sensor out of range - ECT
Guessing this might mean i'm low on coolant?
- 536 - Brake On/Off Circuit Failure/Not Actuated During KOER
C/R
Since when i have to brake hard my parking brake light comes on someone said i might be low on fluid, could this trigger a code?
-538 - Insufficient RPM Change During KOER Dynamic Response Test
R
Ok this one just confuses me, i've never had a problem with the RPMs on the truck.
-214 - Error in Cylinder ID (CID) circuit or signal - Ignition Systems
I already pulled this one and when i had it in the shop to get a new shock mount installed i had them run the engine codes, they said they never found a problem it was just continuos memory codes. Should i take it back to the shop? clear the codes?
-543 - Fuel pump monitor circuit shows no power - Power / Fuel Pump Circuits
-556 - Fuel pump relay primary circuit fault - Power / Fuel Pump Circuits
Ok please correct me if i'm wrong, but if the fuel pump relay failed the pump would get no power and the truck wouldn't start. The relay caused past problems and it was replaced and i replaced the fuel pump, maybe 2-3 months ago.
Help as always is appreciated.
