Monitor heater model 2400 is giving a e 15 trouble code what does this mean ??? found that may have to do with low voltage but nothing has changed and it has worked fine for years ????????

the code is P0209. They are giving you the gears. Nothing to do with Catalytic converter which is between $210 and $400 to replace. Cat is P0420 code. All these codes can be found on Google

What the P0209 code means. The meaning of the P0209 code is that the fuel injector circuit was found to have out of range voltage or resistance. This out of range performance is detected by the Engine Control Module (ECM) and this causes the Check Engine Light to be triggered.

E14 Flame failure: There are obstacles at circulation air inlet or outlet. Fan cage is clogged with dust. Gas pressure dropped when other gas appliances are turned on. (this may also apply to K1 fueled units if you have another K1 based heater)

Here are the rest of the fault codes I found:

Digital Display Reason of indication Trouble Point
E01 At pre-purge, flame rod is sensing flame when there should be none. Flame sensing circuit, grounded flame rod or pinched wire. E05 After power on, power supply to the microprocessor timing circuit is incorrect. Timer clock circuit bad or power cycles (hertz) to unit above or below acceptable levels.
E06 A starting of operation, the circuit to drive photo triac of solenoid pump is malfunctioning. Solenoid pump control circuit has a malfunction.
E08 Revolutions per minute of combustion blower are malfunctioning. Combustion blower or combustion blower control circuit has a malfunction.
E13 No ignition. Failure of ignitor, solenoid pump or circuit board. Incorrect wiring or flame rod touches to burner parts. Air pressure switch or overheat open.
E15 Power supply voltage too low. Voltage too low or power detector circuit has a malfunction.
E16 Load failure of combustion blower motor Flue pipe is restricting air flow.

it should be the o2 after cat converter ----and the following information courtesy of OBDP0037 HO2S Heater Control Circuit Low B1S2 OBD-II Trouble Code Technical Description Article by Dale Dale Toalston ASE Certified Technician Generic: HO2S Heater Control Circuit Low (Bank 1 Sensor 2) Nissan: Heated oxygen sensor (HO2S) 2 Bank 1 - heater voltage low What does that mean? Heated Oxygen sensors (HO2S) are inputs used by the PCM (Powertrain Control Module) to determine oxygen content in the exhaust system. Bank 1, sensor 2 refers to the second sensor back on bank 1. The PCM uses the information gained from the Bank 1,2 HO2S mainly to monitor the efficiency of the catalytic converter. Integral to this sensor is a heater element The PCM controls this heater to warm up the sensor to operating temperature. This allows the engine to enter closed loop faster and reduces emissions on cold startup. The PCM continuously monitors the heater circuits for abnormal voltages or in some cases, even amperages. Depending on the make of vehicle, the Oxygen sensor heater is controlled one of two ways. One way is that the PCM directly controls the voltage feed to the heater either directly or via a HO2S relay and a ground is supplied from the vehicle's common ground. The other way would be a fused 12 volt Battery feed (B+) that feeds 12 volts to the heater element anytime the ignition is on and the control of the heater is done by a driver in the PCM which controls the ground side of the heater circuit. Finding out which one you have is important because the PCM activates the heater under various circumstances. If the PCM detects an abnormally low voltage condition on the heater circuit, P0037 may set. Symptoms Symptoms of a P0037 DTC may include: Malfunction indicator lamp (MIL) illumination There will likely be no other symptoms Causes Potential causes of a P0037 trouble code may include: Bank 1,2 oxygen sensor heater element has failed Physical damage to heated oxygen sensor has occurred Control circuit (or voltage feed, depending on system) is shorted to ground PCM Oxygen sensor heater driver has failed === Possible Solutions== Do a visual inspection of the Bank 1,2 HO2S and wiring harness. If there is any damage to the sensor or any damage to the wiring, repair/replace as needed. Make sure wiring is routed away from exhaust. If all appears okay, unplug the Bank 1,2 HO2S and verify that there is 12 volts B+ present with the key on engine off, (or ground is present, depending on the system). Verify the heater control (ground) circuit is intact. If so, remove the o2 sensor and inspect for damage. If you have access to resistance specifications you can use a Ohmmeter to perform a resistance test of the heater element. Infinite resistance indicates an open in the heater. Replace the o2 sensor as necessary.

This is an over heated indicator, what make and model unit.

http://www.obd-codes.com/p0136

O2 sensor voltage is high when exhaust is rich and low when exhaust is lean. The ECM monitors this voltage and increases or decreases fuel injector pulsewidth according to engine fuel/air ratio. If the ECM detects low HO2Sensor voltage for an extended period, it will set P0136 Conditions required to set: HO2 sensor voltage is low for longer than 2 minutes (minutes depend on model of vehicle. Could be up to 4 minutes)
A code P0136 may mean that one or more of the following has happened:

• Faulty O2 sensor leak in exhaust close to O2 sensor
• Short to voltage on O2 signal circuit
• Open in circuit resistance caused by corrosion in connector

Possible Solutions

• Replace the second oxygen sensor on bank 1
• Repair open or short in signal circuit
• Clean corrosion from connector

Check your filter in the fuel line outside if you have one. Also check the strainer in the fuel sump.

Hi,

Thanks for using Fixya!

1. Cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds. To cycle the ignition key ON means to turn it only as far as it takes to get the radio to come on. It does not mean to turn the engine on.

2. Count the number of times the "check engine" lamp on the instrument panel flashes on and off. The number of flashes represents the code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual codes. For example, flash-flash-flash [pause] flash-flash represents the code 32.

A code of "55" represents end of error codes. If this is all you get then no error codes are stored in the computer. This is the normal condition for a neon.
CODE Description of Trouble Code
11 Timing belt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking
12 Direct battery input to PCM was disconnected within the last 50 key-on cycles
13 No change in MAP from start to run
14 MAP sensor voltage too low
15 No vehicle speed sensor signal
17 Closed loop temp not reached or engine cold too long
21 02s sensor problem (oxygen sensor), upstream or down stream
22 Engine coolant temp sensor out of range
23 Intake air temp sensor out of range
24 Throttle Position sensor out of range
25 Idle air control motor circuits, target idle not reached (+/- 200),vacuum leak found
27 Injector control circuit
31 Evap purge flow monitor failure or evap solenoid circuit
32 EGR system failure
33 A/C clutch relay circuit
34 Speed control Solenoid circuits
35 Rad Fan control relay circuit
37 Torque converter clutch solenoid CKT or park/neutral switch failure
41 Generator field not switching properly
42 Fuel pump relay control ckt, Auto shutdown relay control ckt, No ASD relay output voltage at PCM, Fuel level sending unit volts out of range, Fuel level unit No change over miles
43 Multiple/ single cylinder misfire
44 Battery temp sensor volts out of range
46 Charging system voltage too low
51 Fuel system lean
52 Fuel system rich
53 Internal control failure
54 No Cam signal at PCM
55 End of error messages (If you get this only, no errors were found)
62 PCM failure SRI mile not stored
63 PCM Failure EEPROM write denied
64 Catalytic Converter Efficiency Failure
65 Power steering switch failure

So in your case, you are getting error 3255 right? so you are getting error 32 EGR system failure and 55 which is no other error found.

I hope you get this sorted out.
Have a great day sir.

I have a propane monitor heater just installed 2 months ago and I get an e 13 code and the heater won't stay on???
