Hi I have auxhall insignia 1.8 petrol. My car was giving ser ice ESP light but today it has come up with the sign of traction control on dashboard and saying Engine power reduced. Car has lost power. Can...

You might need to take into the service dealer. or
If you are DIY minded you can get an OBD2 Diagnostic tool, about £25 for a basic one,but the sky's the limit. Available from ebay.
My local garage wanted £100 to diagnose, so a good investment.
These have a more accurate fault finding by way of fault codes. Take careful note of all letters and numbers before resetting system. If fault returns then I advise looking up fault codes online and deal with them. If the fault keeps bringing up the fault light, Do not keep resetting. investigate with the help of the fault codes, and repair before resetting.

What is failt code 16988

If this is code 16988/P0604, it refers to Internal Contr.Module Random Access Memory (RAM) Error. This seems to relate to the ECU and may reset if the car is left without power for a while (disconnect the battery). Or it was triggered after the ECU lost power.

If it doesn't disappear, the fault codes should be reset with a VAG-COM tester. If it persists, it needs further diagnostics at the dealer.

Here's a table of VAG fault codes:

Truck goes forward in all gears except park

What a strange statement . I would expect the vehicle to go forward in all gears except park as that is when the transmission is not working and a gear is physically locked by a pawl in the box . I think you meant reverse in which case run the fault codes and look for a reverse solenoid / servo problem or a TCM fault.

Fault finding

If the fault code doesn't reset the problem is not fixed. PERIOD.

I assume you meant to say fouling up??
If so read on.

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Reduce engine power &service stability control comes up intermittenly

When you get these messages it meant sthe control module for this system has detected a fault, you must have the system scanned with a special toot to see what fault code(s) is in memory

I have a 2005 Kia Spectra. The check engine light has been on and i got it checked. What does engine code Po0011 mean?

Hi Po0011 is not a valid code but if you meant P0011 then it refers to an over advanced cam timing fault.

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)
