    fault codes: 22 & 41. the air valve never seems to close after operating temp. is reached.

  • 10ozzy Oct 06, 2010

    Oh yeah, what started all my problems with this is, the circut opening relay quit working.

  • 10ozzy Oct 06, 2010

    cold start injector time switch shows continuity to ground only when cold start injector wire harness is connected.

  • 10ozzy Oct 06, 2010

    22 & 41 Are the trouble codes. Yes the two codes were displayed at the same time. The check engine light never alerted me that something was wrong. The circuit opening relay failed. When I fixed that problem is when the check engine light appeared.

  • 10ozzy Oct 06, 2010

    Also, Ive replaced the TPS and water thermal sensor as well as air mass.

    Both wires at the injector time switch show continuity to ground only when the cold start injector wire harness is plugged in. The time switch shows to have the correct amount of resistance as well

  • 10ozzy Oct 07, 2010

    Sorry I cut out onyou the other night. OK, THW

  • 10ozzy Oct 09, 2010

    I extracted the codes myself. I have a manual that lists Toyota trouble codes: 22

  • 10ozzy Oct 12, 2010

    Actually I have 2 trouble codes. 22

What was the actual trouble codes, as this relates to water temperature sensor (THW) and Throttle Position Sensor (VTA) and both systems could result in faulty or intermittent operation of the cold start injector.

Have these occurred at the same time, or were these diagnosed at different times........worst case it could be ECU related as this is common to both systems......

    what make/model and year is this vehicle >>>??

  • Luke Bradford
    Luke Bradford Oct 06, 2010

    check to see if the cold start injector sprays during crank when cold. If the cold start injector does not spray, locate the cold start injector time switch, ground the Green wire, crank the engine to see if the cold start injector sprays if the vehicle starts up immediately. If it does then you might have a bad cold start time switch.

    ok....what are the symptoms...is the injector working.....is the vehilce hard to start....high idle...?????lets get back to basics

    THW ???? how did you know...was it during a service or do you have a tool to extract codes.....how did it start...the more info I have, the easier it is to assist you

  • Luke Bradford
    Luke Bradford Oct 10, 2010

    OK, so currently you only have the one code, 22...have you diconnnected battery (leave diconnected for 1-2 minutes) to see if code is erased, as you could have set this code with the repair that you performed......

Why does my engine stall when idling bf falcon only does it some times ?


Fuel Injectors
Use an ohm meter to check your fuel injectors (with the engine running), by removing the wire from the injector. Two metal prongs sit inside the connector. Set the meter for the ohm setting. Touch the red meter lead to one contact and the black lead to the other prong. The ohm resistance number should be the about the same for all the injectors. If any injector reading shows a higher or lower than average number, the cause will be a defective injector, which will cause a rough idle. A zero reading will indicate a shorted injector, and must be replaced. You can also use a stethoscope or a long handled screwdriver to place on the injector head. You should be able to hear a clicking sound, telling you that the injector is "pulsing." No clicking sound indicates a dead injector.
Carburetor-Equipped Vehicles
Examine the choke setting on a vehicle equipped with a choke adjusting knob or mechanism. Make sure the choke operates by opening slowly during normal engine warm-up. A choke that fails to open or sticks shut during warm engine running will cause a constant misfire and rough idle. A choke stuck in the open position will not allow an engine to warm up properly.
Trouble Codes
Hook up a portable trouble code tool for your specific Ford make and model. Look for any trouble codes that appear while the engine runs at idle. Write down any code number and look it up in a trouble-code manual. Most times, code numbers can pinpoint the exact system failure or miss in the engine.

1999 lincoln town car trouble code P1151--I have the service engine light on and it seems to have a rough idle like the fuel injectors are not giving it enough gas I have a code description but I don't...


check the HEGO sensor (upstream) first. Check for a broken wire in the harness to the sensor. Good luck. The HEGO sensor in in the exhasut system just past the exhaust manifold.
The downstream sensor is not so important.



P1151 - Lack of HO2S-21 Switch, Sensor Indicates Lean A HEGO sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC P1130

P1130 - Lack of HO2S-11 Switch, Fuel Trim at Limit The HEGO Sensor is monitored for switching. The test fails when the HO2S fails to switch due to circuit or fuel at or exceeding a calibrated limit.
  • Electrical:
    • Short to VPWR in harness or HO2S
    • Water in harness connector
    • Open/Shorted HO2S circuit
    • Corrosion or poor mating terminals and wiring
    • Damaged HO2S
    • Damaged PCM
  • Fuel System:
    • Excessive fuel pressure

2002 ford f450 7.3 diesel runs ruff and has trouble code p1316 any ideas


P1316 Injector Circuit/IDM Codes Detected .....FJ9 DIAGNOSTIC TROUBLE CODE (DTC) P1316 INDICATES THAT CODES ARE STORED IN THE IDM
Possible causes:
Injector(s) or circuit(s)
Open or shorted IDM enable circuit
Open/short in EF circuit
Open/short in FDCS circuit
IDM relay
IDM powering circuits
IDM
PCM
Check for other codes.
Key on, engine off.
Perform KOEO On-Demand Self Test.

This tells me that the IDM DOES store codes.
Trying to make sense of this. Which test will then give me the codes stored in the IDM? I am pretty sure we did the self test and did not get additional codes

ODB-II Trouble Code of 1151


P1151-Lack of HO2S-21 Switch, Sensor Indicates Lean
A Heated Exhaust Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.

A code P1151 may mean that one or more of the following has happened:
Electrical:
  • Short to VPWR in the harness or HO2S
  • Water in the harness connector
  • Open/shorted HO2S circuit
  • Corrosion or poor mating terminals and wiring
  • Damaged HO2S
  • Damaged PCM
Fuel System:
  • Excessive fuel pressure
    Leaking/contaminated fuel injectors
    Leaking fuel pressure regulator
    Low fuel pressure or running out of fuel
    Vapor recovery system
Induction System:
  • Air leaks after the MAF
  • Vacuum Leaks
PCV system:
  • Improperly seated engine oil dipstick
EGR System:
  • Leaking gasket
  • Stuck EGR valve
  • Leaking diaphragm or EVR
Base Engine:
  • Oil overfill
  • Cam Timing
  • Cylinder compression
  • Exhaust leaks before or near the HO2S(s)
Do you have any running or driveability problem, with this code usually you will not, check these things and makes repairs as necessary, not all of these will be wrong but at least one may be wrong, let me know what you find, hope this helps
