Blowing the 15 amp fuel heater fuse

I had a check engine light with a 0540 code and was told to replace the intake air heater relay. The first cold morning I get the light again and on investigation find the 15 amp fuel heater fuse is blown. I replaced the fuse and the next cold morning the code is set and the fuse is blown.

SOURCE: Cooling Fan Fuse

Sounds like a short in the wiring, or a bad fan motor drawing too much current. Check the wiring for shorts, if none are found, replace the fan motor.

The air vents are control by vacuum line and or linkage.

Listen for hiss or feel for vacuum leak under the dash,

Feel for broken linkage(s) that are close to the vents.


WORK BACKWARD if you have small hands to feel out where is the missing link.

SOURCE: 15 amp fuel pump fuse


Welcome to FixYa.com


I would pull the fuel pump fuse and check , with an ohm meter, to ground to see if you have continuity if you do trace the wire back to fuel pump. too, fuel pump may have internal short. replace pump

Did you replace the fuse ? If yes, does it blow after driving ? Sounds like you may have a main power wiring problem, could be shorting to ground. Do you have any codes or an engine light on ?

87 K5 was running yesterday this morning went to leave and dome light, headlights, check engine light and fuel pump arent working.


It has to do with the secondary air intake. first check for any cracks or leaks in the air intake system. most cars have a plastic routing tube that cracks or gets a hole in it from friction . could be even a bad clamp.check these places first. you might want to disassemble the whole air intake hose apparatus so you can really see whats going on on the bottom side.good luck ,and give me a rating if it helps,Gary

Code p1659


ok , you scanned or Autozoned it, if latter?, fail you do.
did they write it down wrong?
the code must be told accurately, (im sure you know that)

this code needs honda only meanings, P1
Electronic Throttle Control System Control Relay Off Malfunction
blown 7.5a fuse #15?
baring a simple fuse.
read the FSM./
the FSM covers this code, what to do and to find which part is
bad , not guessing, the ECU cant tell you what part is bad or dirty.
it only tells you what tests failed.
read the FSM or take the car to any ASE certified Mechanic.
this car is Throttle by wire. technology. (a pain , the TSB proves it.)

ever heard of a TSB? all good mech read them first
here is one example, on topic. too.
quote: (look up you car, and YOUR TSBs, read them all)

MIL Comes On With DTC P1659 TSB 05-008
SYMPTOM
In cold temperatures, the MIL comes on with DTC P1659 (electronic throttle control system control relay OFF malfunction). PROBABLE CAUSE Moisture inside the throttle control relay may freeze. This would cause the relay to fail, storing DIG P1659 along with any of these DTCs: P0135: Rear Air Fuel Ratio (A/F) Sensor (Bank 1, Sensor 1) Circuit Malfunction, P0141: Rear Secondary Heated Oxygen Sensor (Secondary HO2S, Bank 1, Sensor 2) Heater Circuit Malfunction, P0155: Front Air Fuel Ratio (A/F) Sensor (Bank 2, Sensor 1) Heater Circuit Malfunction, P0161: Front Secondary Heated Oxygen Sensor (Secondary H025, Bank 2, Sensor 2) Heater Circuit Malfunction, P0498: Evaporative Emission (EVAP) Canister Vent Shut Valve Control Circuit Low Voltage. CORRECTIVE ACTION Replace the electronic throttle control relay, the air/fuel sensor relay, and the starter cut relay.

2003 SDi Volkswagen Polo, hard to start in mornings. Changed air filter, glo plugs, fuel filter and no change. I read the code with the OBD scan tool and I got code PO113 IAT sensor 1 Circuit High inp


Have that sensor checked or replaced. If the computer gets the wrong input signal from the intake air temperature sensor, it may not realize the engine is cold and not delivering enough gas at start-up.

I have a 2000 chevy s-10 blazer 4.3L w/the codes p0542 and po543 coming up and i changed the fuel pump and the fuel filter and they still wont go away, so what do i do now?


Here is the description for code 543. Code 542 is for the heater not working.

P0543 GMC Description The engine control module (ECM) uses an intake air heater (IAH) to warm the incoming air for proper cylinder combustion. The ECM grounds the control coil of the IAH relay to energize the heater during cold operation. The ECM sends a bias voltage on diagnostic circuits one and two. If this voltage is not pulled low when the relay is OFF, or is high with the relay ON, DTC P0543 will set. The ECM will only store info on first failure, It triggers the SES light on the second failure.
