dirty throttle body

 

 

Isuzu Work done

problems that I have had

P0014 - -

Isuzu

Exhaust Camshaft Position Timing - Over-Advanced (Bank 1)

Possible causes

- Dirty Oil

- Low engine oil level

- Variable Camshaft Timing harness open or shorted

- Variable Camshaft Timing circuit poor electrical connection

- Failed Camshaft Actuator

MY FIX:

I removed the bolts pulled it out as far as I could, without removing the power steering unit - - spayed crab cleaner on it.

Had the oil changed.  BEEN 2 Years and that code has not returned

P0506 - -

Isuzu

Idle Air Control System RPM Lower Than Expected

Possible symptoms of OBD code P0506

Most likely the only thing you'll notice is the idle speed is lower than normal so it will likely be rougher. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.

Causes

Possible causes of OBD code P0506

A P0506 DTC trouble code may be caused by one or more of the following: A vacuum leak An air restriction in the intake air path or exhaust A faulty positive crankcase ventilation (PCV) valve Damaged/failed/dirty throttle body Internal engine problem Failed PCM

My FIX:

for less than $4.00 - I got a can of B-12  put in gas tank that cleaned the Fuel injectors.

For less the $4.00 - I got crab cleaner and cleaned out the throttle body that was less than 20 min work. 

Less than 8 miles of driving the engine light went off and I passed smog. 

From time to time that code will return - do to the lower priced gas I use

Easy fix - - crab cleaner and cleaned out the throttle body (2 bolts 2 hose clamps)

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Pulley went out

Replaced Pulley and fan belt

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Water pump leaking

Replace water pump and fan belt

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------

P0128

Isuzu     Coolant Thermostat (Coolant Temp Below Thermostat Regulating Temperature)

Possible causes

- Leaking or stuck open thermostat

- Low engine coolant level

- Insufficient warm up time

- Faulty engine coolant temperature sensor

- Engine coolant temperature sensor harness is open or shorted

- Engine coolant temperature sensor circuit poor electrical connection

MY FIX:

Replace  thermostat - note this is located on the right side of engine (follow the lower water hose) (part under $30.00) AutoZone

Note: Normally you will find the thermostat on the top side of the engine – (Top RADIATOR HOSE)

Not on this Isuzu, it’s on the right lower side of the engine. (Lower Radiator Hose). I had to replace the fan Clutch so the fan and clutch was already out of my way – removed the bracket above the alternator – removed the 3 bolts for the alternator and laid the Alternator out of the way (did not disconnect it) now I had room to get to the two (2) bolts for the thermostat.

P0463 

Isuzu    

Fuel Level Sensor A Circuit High Input

Possible symptoms of OBD code P0463

- Engine Light ON (or Service Engine Soon Warning Light)

Causes

Possible causes of OBD code P0463

- Fuel level sensor circuit harness or connectors is open or shorted - Fuel level sensor may be faulty The Error code is generally activated on detection of the following conditions: An excessively high voltage is sent from the sensor is sent to ECM.

Possible Solutions

Replaced fuel level sensor.

MY Symptom, fill up the gas tank - shortly later gauge will show empty

some time it would work - some times it would just quit working, would not read correctly. not a problem I just fill up every 330 miles

Now over a year later it just don't work at all, giving engine light and code P0463.

MY FIX:

Drop gas tank, replace the sending unit (part under $55.00) internet

Possible causes

- Faulty cooling fan clutch

- Faulty control unit

Looking at the fan clutch, can see that there is some play - the bearing are going out

MY FIX:

Fixed that last 3 codes P0128  P0463  P0495

Should Passed Smog Now

24 July 2013 Breaks Front brakes done 24 July 2013

 

Rear Brakes done 27 July 2013

May 9th 2013

There was a slight delay starting – almost like a low battery. Went to Wal-Mart when leaving the truck would not start. Strange – turn key on all gauges went to normal position, turn to start nothing happened – release key all gauges went to the far left for a few sec – then returned to normal position – VERY STRANGE.

Battery 100% good – only thing left was the starter. AutoZone had one for under $90 .

Brother-in-Law Ringo Helped me (thank God as I had been stressed all week) replaced starter and now working fine.

When the starter goes out – IT GOES OUT WITH LITTLE TO NO WARNING.
