Where is the control valve - Cars & Trucks

1700 is a generic code for many makes and models referring to a transmission issue.1751 is directed to the shift solenoid valve b. May be able to replace just that solenoid and be ok. Cheaper than a transmission.

without knowing your make or model:

EGR Valve Position Sensor Signal Too Low

The oil control valve is used by the computer to change valve timing.
There is a problem in that the computer can not control the valve to change valve timing. Could be the control valve, sludge in the engine, or a wiring problem between the control valve and the computer.

Here is the definition for code 11.

P0011 NISSAN Description
Problem with the intake valve timing control solenoid valve.
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve.

The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range.

The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position.
Could be a problem with the control valve, oil flow to the valve, or one of the cam or crank sensors.

P1136 NISSAN - Intake Valve Timing Control Solenoid Valve Circuit Bank 2
Possible causes- Intake valve timing control solenoid valve bank 2 circuit is open or shorted.
- Intake valve timing control solenoid valve bank 2 circuit connectors
- Intake valve timing control solenoid valve bank 2 Tech notes Since the Intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code.

P1136 NISSAN - Intake Valve Timing Control Solenoid Valve Circuit Bank 2

Possible causes- Intake valve timing control solenoid valve bank 2 circuit is open or shorted.
- Intake valve timing control solenoid valve bank 2 circuit connectors
- Intake valve timing control solenoid valve bank 2
P1124 NISSAN - Throttle Control Motor Relay Circuit Short

Possible causes- Throttle Control Motor relay harness is open or shorted
- Throttle Control Motor relay circuit poor electrical connection
- Fualty Throttle Control Motor relay

If you can supply me with all the codes your vehicle is showing, I can assist you. As far as the P1111 DTC goes I have listed the info below with some possible solutions.

P1111- Intake Valve Timing Control Solenoid Valve Circuit Bank 1

Intake valve timing control solenoid valve is activated by ON/OFF pulse duty (ratio) signals from the ECM. The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position. The code is triggered when an improper voltage is sent to the ECM through intake valve timing control solenoid valve. Since the Intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code.

Possible Causes:
- Intake valve timing control solenoid valve bank 1 circuit is open or shorted.
- Intake valve timing control solenoid valve bank 1 circuit connectors
- Intake valve timing control solenoid valve bank 1
- Dirty Oil

Possible Solutions:
- Change Oil
- Replace Intake valve timing control solenoid valve

sorry but your code reader is not reading manufacturers codes ,if an american market vehicle then you should be able to read them but if this is a europeon model then how did you manage to get this code??

P0235....Turbo/Super Charger Boost Sensor 'A' Circuit

this is a generic code if its any help

Accelerator Pedal Position Error.

P2138 - Accelerator Pedal Position Sensor Circuit Range / Performance Problem

Clear the code - if it recurs, change the sensor.


Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question.

may just need cleaning with carb cleaner.

here is 1996, oldest I have:

Section 03-14: Engine Controls, Electronic 1996 Taurus, Sable Workshop Manual
REMOVAL AND INSTALLATION Idle Air Control (IAC) Valve Removal

1. Disconnect battery ground cable (14301). Refer to Section 14-01 .
   

1. Disconnect the engine control sensor wiring (12A581) from the idle air control valve (IAC valve) (9F715) at the idle air control valve electrical connector.
   

1. Remove the two idle air control valve retaining bolts.
   

1. Remove the idle air control valve and idle air control valve gasket.
   

Installation

1. NOTE: If scraping is necessary, be careful not to damage idle air control valve gasket surfaces, or drop material into intake manifold (9424) or throttle body (9E926) (depending upon application).
   
   Clean idle air control valve gasket mating surfaces.
   

1. To install idle air control valve, reverse Removal procedure.
   

1. Tighten the idle air control valve retaining bolts to 8-12 Nm (71-106 lb-in).
