Replacement of information gauges
The gauge of temperature of a cooling liquid of the engine (EATS)
|
|
Before to start procedure performance wait definitive cooling of the engine! |
Components of installation of gauge ECT
On petrol models V8 the gauge is under a cover of the case of a throttle (address to an illustration above) in the top part of the inlet pipeline. The gauge rearranges from itself термистор which resistance varies in inverse proportion to temperature of a cooling liquid. The description of procedure of check of the gauge is resulted in Section Information gauges - the general information and check of serviceability of functioning.
|
|
1. For gauge removal merge cooling liquid and uncover throttle cases. Remove a flange of an inlet air line from the throttle case. Remove the throttle case for what disconnect from it a cable of an accelerator and give two bolts and two nuts of fastening.
|
|
The old lining can be thrown out – for installation it is required new. |
2. Disunite a contact socket of gauge ECT, then cautiously turn out assemblage from the landing nest.
|
|
Try to address with the gauge eats extremely cautiously, – its damage is capable to affect serviceability of functioning of all power supply system. |
|
|
Old the sealing ring of the gauge can be thrown out – for installation it is required new. |
3. Installation of the new gauge should be made as soon as possible for the purpose of minimisation of losses of a cooling liquid. Tighten the gauge and fixture of the case of a throttle with demanded effort. In summary fill in cooling liquid, start the engine and be convinced of absence of leakings. |

Gauges of an air stream
Gauge MAF
Gauge MAF is placed in an air inlet sleeve. The sensitive element of the gauge is a thread накаливания. The gauge serves for definition of weight soaked up in the engine in unit of time air. The description of procedure of check of the gauge is resulted in Section Information gauges - the general information and check of serviceability of functioning.
|
|
1. Disconnect from gauge MAF electroconducting and separate assemblage of an air cleaner from an air inlet sleeve (see the Head of the Power supply system and release of the fulfilled gases).
|
|
2. Give fixing screws and remove assemblage of gauge MAF from an air cleaner (address to an accompanying illustration). |
3. Installation is made upside-down. |
|
Gauge IAT
Gauge IAT is built in the case of gauge MAF and not separately to replacement is not subject.
Ljambda-probes
|
|
Owing to temperature compression of components of system of release of the fulfilled gases at its cooling ljambda-probe extraction can appear is interfaced to certain difficulties. In order to avoid risk of damage of the gauge at its reversing, preliminary warm up the engine within one-two minutes. Be careful, do not burn.
|
On models V8 4 ljambda-probes, – two верхнепоточных, established ahead (on a stream) каталитических converters and two нижнепоточных, screwed in system section more low (on a stream) каталитических converters are established. Gauges trace level of the maintenance of oxygen in the fulfilled gases of the engine. The description of a design and procedure of check of gauges is resulted in Section Information gauges - the general information and check of serviceability of functioning.
At service of ljambda-probes it is necessary to observe special safety measures:
- The ljambda-probe is equipped tightly built in in it, the equipped contact tip, an electroconducting piece, performance of which attempts of a detachment can lead to an irreversible exit of a probe out of operation;
- Try not to suppose hit in jalousie of a probe or in its electric socket of a dirt and greasing;
- Do not use for ljambda-probe clearing any solvents;
- Address with a ljambda-probe extremely carefully, do not drop it and try not to shake;
- The silicone protective cover should put on on the gauge strictly definitely not to be fused and not to break serviceability of functioning of a probe.
|
|
1. Disconnect a negative wire from the battery.
|
|
If the stereosystem established on the car is equipped by a security code before to disconnect the battery make sure that have a correct combination for audiosystem input in action! |
2. Поддомкратьте the car also establish it on props.
3. Remove the thermofilters blocking access to subject service to the oxygen gauge. Disconnect from the gauge electroconducting.
4. Accurately turn out bolts of fastening of a ljambda-probe to an element of system of release (to a final collector or an exhaust pipe).
5. At probe installation it is necessary to grease its carving part with antitaking hermetic.
|
|
The carving of the new gauge is usually already processed by corresponding structure. |
6. Establish a probe on the regular place and strongly tighten it.
7. Restore initial connection of electroconducting.
8. Lower the car and make its trial runs. Make sure of absence in memory OBD of codes of malfunctions. |

The gauge of position throttle заслонки (TPS)
Site and fastening TPS
The representing potentiometer of variable resistance TPS fastens on the case of a throttle and is connected directly to an axis throttle заслонки (address to an illustration above). The description of a design and procedure of check TPS is resulted in Section Information gauges - the general information and check of serviceability of functioning.
|
|
1. Disconnect from the gauge electroconducting.
|
|
Probably, for the purpose of providing of access to a contact socket of the gauge, it is necessary to remove an inlet air line. |
2. Turn out fixing screws and remove TPS from the throttle case.
3. At gauge installation track hit of directing uvulas in reciprocal grooves on an axis throttle заслонки. Check up gauge TPS.
4. Installation is made upside-down. |
|
The gauge of position of a cranked shaft (СКР)
Components of installation and gauge CKP check
|
|
1. Gauge CKP site is specified in illustrations above. For the purpose of providing of access to a fixing bolt remove protection картера. Disconnect from the gauge electroconducting and give a bolt of its fastening to the oil pump.
2. Installation is made upside-down. Tighten a bolt of fastening of the gauge with demanded effort. |
|
The gauge of position of a camshaft (СКР)
|
|
1. The gauge is established in the left head of cylinders (address to an illustration above). For the purpose of providing of access to a fixing bolt merge cooling liquid and remove belts of a drive of auxiliary units. Disconnect from the gauge electroconducting and give a bolt of its fastening and a hairpin.
2. Installation is made upside-down. Tighten a bolt of fastening of the gauge with demanded effort. |
|
Detonation gauges
|
|
Before to start procedure performance wait definitive cooling of the engine. |
|
|
On engines 2UZ-FE on each head of cylinders it is established on one gauge of a detonation. |
|
|
The site of the gauge of a detonation is presented on an accompanying illustration. |
|
|
1. For removal of the gauge of a detonation merge cooling liquid and remove an inlet air line.
2. Uncover a belt of drive ГРМ, covering cogwheels of camshafts.
3. Remove the top part of the inlet pipeline and a regulator of pressure of fuel.
4. Remove the inlet pipeline.
5. Remove water перепускную a tube and disconnect conducting of gauges. Remove gauges.
6. Installation is made upside-down. Having screwed gauges, tighten with demanded effort. Fill in cooling liquid. |

The gauge of speed of movement of the car (VSS)
The description of a design and procedure of check VSS is resulted in Section Information gauges - the general information and check of serviceability of functioning.
|
|
1. Turn out fixing bolts, disconnect electroconducting and remove the gauge.
2. Installation is made upside-down. |
