My monitor 2200 heater is leaking fuel what could be the problem

P005x - HO2S Heater Resistance (Bank 1, Sensor 1), (Bank 1, Sensor 2), (Bank 1, Sensor 3), and (Bank 2, Sensor 1) Description: Heater current requirements too low or high in the heated oxygen sensor (HO2S) heater control circuit (HO2S11, HO2S12, HO2S13, HO2S21). Possible Causes:

• VPWR circuit open
• HO2S heater circuit open
• HO2S heater circuit short in the harness
• Damaged HO2S heater

Diagnostic Aids: Inspect the connectors for signs of damage, water ingress, or corrosion. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test DW .
P0060 - HO2S Heater Resistance (Bank 2, Sensor 2) Description: Heater current requirements too low or high in the heated oxygen sensor (HO2S) heater control circuit (HO2S22). Possible Causes: See the possible causes for DTC P005x. Diagnostic Aids: See the diagnostic aids for DTC P005x. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test DW .
P0455 - Evaporative Emission System Leak Detected (Gross Leak/No Flow) Description: The powertrain control module (PCM) monitors the complete evaporative emission (EVAP) control system for no purge flow, the presence of a large fuel vapor leak, or multiple small fuel vapor leaks. System failure occurs when no purge flow, which is attributed to fuel vapor blockages or restrictions, a large fuel vapor leak, or multiple fuel vapor leaks are detected by the EVAP running loss monitor test with the engine running, but not at idle. Possible Causes:

• After market EVAP hardware that does not conform to the required specifications
• Disconnected or cracked fuel EVAP canister tube, EVAP canister purge outlet tube, or EVAP return tube
• EVAP canister purge valve stuck closed
• Damaged EVAP canister
• Damaged or missing fuel filler cap
• Insufficient fuel filler cap installation
• Loose fuel vapor hose/tube connections to the EVAP system components
• Blockages or restrictions in the fuel vapor hoses/tubes
• Fuel vapor control valve tube assembly or fuel vapor vent valve assembly blocked
• Canister vent (CV) solenoid stuck open
• Mechanically inoperative fuel tank pressure (FTP) sensor

Diagnostic Aids: Check for audible vacuum noise or significant fuel odor in the engine compartment or near the EVAP canister and fuel tank. Application Key On Engine Off Key On Engine Running Continuous Memory All - - GO to Pinpoint Test HX . P2270 - O2 Sensor Signal Stuck Lean - Bank 1, Sensor 2 Description: The downstream heated oxygen sensor (HO2S) is forced rich and lean and monitored by the powertrain control module (PCM). The test fails if the PCM does not detect the output of the HO2S in a calibrated amount of time. Possible Causes:

• Pinched, shorted, and corroded wiring and pins
• Crossed HO2S wires
• Exhaust leaks
• Contaminated or damaged HO2S

Diagnostic Aids: Application Key On Engine Off Key On Engine Running Continuous Memory All - GO to Pinpoint Test H . GO to Pinpoint Test H .

Replace rubber lines to injection fuel pump.

If as you say it is a1986 model it will have a carby and no injectors . a worn needle and seat can cause a fuel leak but the engine will run rough or not at all .if the engine runs ok check the fuel lines for a leak. trace the fuel line back to the pump an check for leaks.

Check the pump pressure & purge the pump

It sounds like you have a fuel problem, check to see if there is some kind of blockage in the line or at the tank value.

E-13 - No ignition. Water in fuel line, no fuel in sump, blocked pumpand/or sump filter. the pump doesn't know water from kerosene it will pumpthis. Water doesn't burn so it will knock out the flame and lock out theheater. You can add a quart of denatured alcohol to 150 gallons of kerosene.the alcohol will emulsify the water enabling it to burn.
THERE'S A RED BUTTON THAT RESETS THE FLOAT. press this down. All it does isrelease the float. There's a sheet metal tab on the float and a magnet on thebottom of the button

Does it smell like raw kerosene or exhaust. If it smells like kerosene it sounds like you may have a fuel leak. If you can remove the grill, look inside and check for any kerosene in the bottom and in the tray under the heater. You should also check your fuel line for leaks. If it smells like exhaust look inside and on back of the heater for any black soot marks. There are a couple of o-rings, 1 in the exhaust connection in back of the heater and 1 in the flue pipe where the exhaust from the heater connects. There's also several gaskets in the combustion chamber that could be leaking. Hope this helps. If you need any more info, you can send me an email ([email protected]).

Hi Edward - I have the same heater and it just did the same as yours. The booklet doesn't list what the codes mean (how dumb is that?) but in the troubleshooting section it does list the problem (heater extinguishes after lighting) and a solution that worked in my case. First of all, I went outside to where it vents and cleaned out a big bubble of soot. (The book says to gently clean with a brush). Then, on the right side of the heater there is an inset button - "Press fuel set lever on lower right hand side of the cabinet and release slowly 2 or 3 times".

Your problem is either air pocket in fuel line or empty fuel tank. OR there is an obstruction of combustion air intake system or combustion fan failure (which I'm assuming was solved when I cleaned the soot out of the outside vent).

Hope this helps, if you haven't gotten if fixed yet.

EE13 on a Monitor is one thing. The same code on a Toyostove is completely different. A Monitor EE13 means there was no flame at ignition. On a toyostove EE13 is the burner thermistor.

On the Monitor I would check my fuel tank. On the Toyo you may have to have the dealer help you, as it could be something easy like a very cold day or more complicated as a main circuit board.
