Due to the lack of info as to what model it is and what engine it has this could be a number of things, but working under the assumption that is ether a td5 or puma the most likely fault is oil creep in the wiring harness. my advice would be to use a can of brake disc cleaner as this leaves no residue and remove all contacts on the injectors and ecu, give them a good spraying over and refit carfully.

No trouble codes just weak injector pulse after ignition cycle..but when starting strong injector pulse..already change crankshaft sensor learning toward camshaft sensor


strong start weak run indicates a power loss during the run cycle
Try changing the ECM with a known good unit as it may have an electronic failure internally
If you have problem cam or crank sensors, normally it will not allow spark for the engine to run

Hi, Had loss of power in Kia Sorento 2006. Changed injectors but it wouldn't start. Checked injectors and put them back but it still won't start. Any ideas? Thanka in advance.


run the fault codes . check for cam/crank position sensor problem. check that the cam shaft is turning (broken timing belt/chain). check immobiliser is operating correctly

You have four fault code there...

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).


Code 23
Notes: For throttle body injected (N/A) models only

Description: Throttle body temperature sensor signal out of range
Power loss light: On
Limp-in mode: Throttle body temperature of 70^F is assumed

Possible Causes
Throttle body temperature sensor failure - The sensor should measure 9,120 ohms to 10,880 ohms at 77^F. This sensor is located on the side of the throttle body, below the throttle plate.

Bad connection or wiring - Check the wiring and connections between the sensor and the logic module (or SMEC). Clean and regrease any corroded connectors with dielectric grease.

Diagnostic Method
Trigger Parameters
- Sensor output less than 0.06V or greater than 4.98V
Results If Component Fails
Fault code 23 is stored, the power loss light is turned on, and the logic module will enter limp-in mode, assuming a throttle body temperature of 70^F.

Code 32
Description: Logic module did not see a change in air/fuel ratio when EGR circuit was activated
Power loss light: Off
Limp-in mode: None

Possible Causes
EGR valve stuck open or closed - If the vehicle fails emmisions, then the valve may be shut. If the enigne runs poorly at low rpm or at idle, the valve may be stuck open. It may be the valve or the transducer valve. Test the transducer valve vacuum output. At idle, the transducer valve vacuum should be mostly bled, and there should be very little, if any vacuum at the output. When the engine is revved, the vacuum should increase. If the transducer is functioning properly, replace the EGR valve.

Bad EGR solenoid or Canister purge/EGR solenoid - The solenoid is located in the right, front fender next to one to three other solenoids. See the Understanding Solenoids page for information about how to test and repair solenoids.

Bad connection or wiring - Check the wiring and connections between the solenoid and the logic module (or SMEC). Clean and regrease any corroded connectors with dielectric grease and repair any shorts.

Diagnostic Method
Trigger Parameters
- The EGR solenoid was deactivated, but the oxygen sensor reading did not change
Results If Component Fails
Fault code 32 is stored.

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 this helps (remember to rate this answer).

Car is hesitating have error code p1391 check engine light is on what does this code mean it is not in the book I just put a crank posistion sensor and that fixed it ,now it is doing it again only worse...


p1391 is intermitant loss of signal from crank sensor and cam sensor--change sensors!! change cam sensor first. good luck!! then try it, if still same way. change crank sensor.

My engine management light is permantly on. How can I reset it?


Hi this could be many things.

Most likely it will be the air mass sensor, the lambda sensor, or the EGR valve, although if the EGR valve has gone you will notice a big loss in power.
You will have to get the car put on a code reader to be sure.
