If the wiring is okay your sensors have failed.

My 2008 cadillac srx engine light came on and engine power reduce took it to the dealer so they changed the crank shaft sensor but its still not working, can you please help me


if they didn't read the fault codes before starting work, they are repairing by replacement and that is not good
if a sensor is faulty and it could be a cam shaft sensor as well as a crankshaft sensor , normally it misfires or stops altogether
the ECM is in limp mode and that reduced the engine power and if there was a sensor problem it would not just reduce power and put the light on but would show up in a define manner
engine lights also come on it there is a transmission problem and that will also initiate the limp mode
have the fault codes read to determine the faulty part/ sensor

Check engine light is showing and does not have enough power. What do I do?


get CEL scanned at a garage and have them look up the code. It could be almost anything but usually lack of power means its in limp home mode and there is a critical sensor that has failed, like cam or crank sensor or ignition controller.

I have a 2007 Vulcan 1600 classic and the cooling fan won't run. any ideas on what to test and how to test it? Jim


This fan runs of a heat sensor..The sensor may be gon......Trace the wires and see if their is power from the sensor when it gets worm and also powet to the sensor........Power to the sensor is good but power not showing from the sensor after temp light or gauge shows time to cool means the sensor is unservicable..Hope this helps.

The computer codes are 121155. What does this mean?


Code retrieval can be accessed by the ignition key or by a diagnostic readout box(DRB).To obtain the codes using the key method,set the park brake,and put the vehicle in Park/neutral.

Some 95 and later OBDII vehicles, you may be able to retrieve OBDII codes with this procedure, if equipped with digital dash:

* Turn the ignition key ON,OFF,ON,OFF,and finally ON again(ENGINE NOT RUNNING)
* The codes will start to flash on the POWER LOSS or CHECK ENGINE light.
* FLASH,pause,FLASH,FLASH=code 12

The codes showed are...


Fault Code 12
Description: Memory standby power recently lost
Power loss light: Off
Limp-in mode: None

Possible Causes:* Battery or power line recently disconnected - This code is normal if the electrical system has been worked on or the battery has recently been disconnected. It will be removed after 15 ignition switch on/off cycles.
* Low system voltage, bad battery or battery terminals - If the system recently had a power drop (due to a dead battery or bad alternator), this code will appear. If the battery terminals are bad and the engine was jumped, this code will appear.
* Bad connection or wiring - Check the wiring and connections between the battery, power module, and logic module (or SMEC). Check all fusible links and power connectors to the battery. Clean and regrease any corroded connectors with dielectric grease and repair any shorts.

Diagnostic Method
Trigger Parameters
- Logic module receives power after previously not having power


Results If Component Fails

Fault code 12 is stored. The logic module is basically telling you that it has lost power and will not remember any previously stored codes or engine sensor table data. The code will be removed after 15 ignition on/off cycles and the logic module will use default values for all look-up tables as a starting point until it "learns" the attributes of the engine.


Fault Code 11
Description: Engine not cranked since last reset or no ignition reference signal detected during cranking
Power loss light: Off
Limp-in mode: None

Possible Causes:
* Engine hasn't been cranked since last reset - Power was removed from the logic module (disconnected or dead battery, etc.) and the logic module has no memory of seeing a signal from the ignition reference sensor. Crank the engine and check for the code again. If the logic module saw a signal, the code will be cleared. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working.
* Bad connection or wiring - Check the wiring and connections between the hall effect sensor (located underneath the distributer cap) and the logic module. Check the continuity of the two 3 conductor cables coming out of the sensor--these are prone to fatiguing and breaking inside the insulation where they exit the sensor if the cables are not properly tied down. You may be able to resolder them. Clean and regrease any corroded connectors with dielectric grease and repair any shorts. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working (see above).
* Hall effect sensor failure- Check the ignition reference sensor and fuel injector sync sensor cables. They are the two, flat 3 conductor cables coming out of the sensor at the base of the distributer cap. These often fatigue where they exit from the sensor. Upon replacing the sensor, make sure the cables are clipped or tied to the distributor cap shroud (or elsewhere) so they do not swing around. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working (see above).

Diagnostic Method
Trigger Parameters
- Computer has been reset
- No signal from the ignition reference sensor has been detected

Results If Component Fails
Fault code 11 is stored and the engine will not start (even if the ignition reference sensor is working). A running engine will stall, but no code will be stored. The logic module must be reset and the engine cranked to see if the sensor is working.


Fault Code 55
Description: End of message
Power loss light: Off
Limp-in mode: None

Possible Causes:
* No further fault codes are stored. If this is the only code received, then there are no codes stored in memory. This code will always be given, even if nothing is wrong. If you do not get this code, then you may not be retreiving the codes properly, or the power loss light may be burnt out. The light should come on for 1 second when the ignition is initally turned on as a bulb test.

Diagnostic Method
Trigger Parameters
- No further codes in memory


Hope helps (remember comment and rated this)

Why does reduce engine power light comes on chevy


That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.

Attention Light Is Rapidly Blinking Orange


sorry I got it, usually you may try:
1) check all paper road no paper inside include the area betweem input tray and cartridge unit the area wetween cartridge and fuser unit and output tray.
2) check 4 sensor input sensor near the input tray roller, marging sensor between input roller and cartridge unit, cartridge sensor at oneside of cartridge unit body, fuser sensor near fuser roller. usually need to clean or adjustment the position.
3) check input roller and cartridge unit and fuser unit at running condition when the power on.
anyone nothing running show error light blink, also show the hardware trouble if all sensors are normal.
