P1391 Glow Plug Circuit Low Input (Bank #1)

  • DTC P1391 or P1393 will set when the monitor indicates that all four glow plugs are not being powered on that bank. An open in the glow plug circuits, glow plug relay, glow plugs or monitoring circuit could be the possible causes.

    Both DTCs P1391 and P1393 together will set when the monitor indicates that all eight glow plugs are not being powered. An open in all glow plug circuits, the glow plug relay, glow plugs, fusible links or all three monitoring circuits could be the possible causes.
  • Possible causes:
    • glow plug relay
    • glow plug shunt
    • open in glow plug circuit(s) or monitoring circuit(s)
    • glow plugs
    • PCM

SOURCE: Help 95 ford contour obd-1 error 335

I was reading in one of my repair manuals and it says in there that there could be a block where the exhaust gas pressure sensor is. There could be a blocked inlet hose. Or it could be the ECM.

SOURCE: my check engine light is

Hi,

Code 32 indicates a problem with the Exhaust Gas Recirculation (EGR) system, there are three different descriptions for this code so the failure can be as simple as a broken vacuum line or as involved as replacement of the valve and cleaning out of the EGR passages. A more specific code will be needed in order to assist you further.

Let me know, once done.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

hate to say it but my buddy just had same or very similar problem. His was a bad valve spring. Part is like 10 bucks but if your not a mechanic it can cost anywhere from 150 to 300. He tried the Map sensor, tps, plugs wires, egr and o2 sensors. But my other friend says to remove both battery cables and touch them together for 5 mins and this may reset your computer. try that first. He has a 01 caravan

Code P1391, replaced camshaft and crankshaft sensors, plugs and wires, rotor, and a couple fuses, can a loose or bad distributor be the cause for this code?


DIAGNOSTIC TROUBLE CODE (DTC) P1391: "INTERMITTENT LOSS OF CMP OR CKP"
This DTC is monitored with the engine cranking or running. This DTC will be stored in the Powertrain Control Module (PCM) when the PCM FAILURE COUNTER reaches 96 failures for 2 consecutive trips.
Posiible causes are: Craknkshaft Position (CKP) sensor improperly installed, defective CKP sensor, defective distributor, defective Camshaft Position (CMP) sensor, defective PCM, defective or broken flywheel, defective connectors or defective wiring.
Proper diagnosis is recommended before replacing ANY parts.

I have code 406 what does it mean?


on youe veicle you have to follow procedures to check O2 sensors
voltage to high more than 3.7 volts
circuit shorted or O2 sensor is no good thats for code 138
code 171 contaminated O2 sensor
406 is your EGR system shorted open thats whats probably causing your O2 sensors to contaminated fix the EGR and clean passage way to intake
