Engine code list

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.

answer courtesy of obd-codes.com Potential causes of a P0026 diagnostic trouble code may include: Low engine oil level or contaminated oil Clogged oil system Malfunctioning control solenoid Malfunctioning camshaft actuator Timing chain/belt loose or incorrectly adjusted Malfunctioning ECM/PCM Possible Solutions Engine oil - Check the engine oil level to make sure engine oil capacity is sufficient. Since the actuators work on oil pressure, the proper amount of oil is critical to ensure proper operation of the VVT system. Dirty or contaminated fluid may cause buildup which can lead to failure of the control solenoid or the camshaft actuator. Control solenoid - The control solenoid for the camshaft can be checked for continuity using a Digital volt/ohm meter (DVOM) using the ohms function, by unplugging the solenoid wiring harness connector and checking the resistance of the solenoid with the (+) and (-) leads of the DVOM on each terminal. Ensure the internal resistance is within manufacturers specifications if available. If resistance is within specifications, remove the control solenoid to verify it is not contaminated, or if there is damage to the sealing O rings to cause a loss of oil pressure. Camshaft actuator - The camshaft actuator is a mechanical device controlled by internal spring pressure and adjusted by oil supplied by the control solenoid. When no oil pressure is supplied, it will default to a "safe" position. Refer to the manufacturers suggested procedure to remove the camshaft actuator from the engine's camshaft to ensure no leaks are present that would cause a loss of oil pressure to and from the actuator's hydraulic supply/return feed lines or within the actuator itself. Check timing chain/belt and components to ensure they are in proper working order and installed in the correct position on the camshaft gear. ECM/PCM - The ECM/PCM commands the control solenoid using a Pulse width modulated signal (PWM) to regulate the amount of on/off time, resulting in a control of the pressure used to move the camshaft actuator. A graphing multimeter or oscilloscope tool is required to view the PWM signal to ensure proper operation of the ECM/PCM. To check the PWM signal, the positive (+) lead is tapped into the ground side of the control solenoid ( if supplied by constant voltage, ground controlled ) or the powered side of the control solenoid (if permanently grounded, positive control ) and the negative (-) lead is attached to a good known ground. If the PWM signal is not consistent with changes in engine RPM, there may be a problem with the ECM/PCM

The Engine Control Module (ECM) uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd, 4th or 5th gear). Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical troubles of the shift solenoid valves and valve body.

code p0313 refers to misfire detected---low fuel level===causes-- fuel system ---mechanical fault ( check fuel pressure, fuel filters and fuel pump)
code p0087 refers to fuel rail /system pressure --too low=== causes --fuel pump,--fuel pressure regulator--fuel supply line blockage--mechanical fault. ( have the fuel system pressure tested.)
The code you have listed as p008A is not in the book and you have not given an make or engine model to refer to in other places. I will refer to the code as p0084 which refers to exhaust valve control solenoid, bank 2--circuit malfunction===causes --wiring--exhaust valve control solenoid---ECM ( this will present as a rough running engine or problem starting/ shutting down

P1782 DODGE - 2/4-OD Pressure Switch Circuithttp://engine-codes.com/p1782_dodge.htmlForum CodePossible causes- Low transmission fluid level
- Dirty transmission fluid
- Faulty 2/4-OD Pressure Switch
- 2/4-OD Pressure switch poor electrical connection
- 2/4-OD Pressure switch circuit is open or shorted
Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shockP1782 DODGE Description The pressure 2/4-OD Pressure Switch is part of the pressure switch of the transmission. The pressure switch are located in the solenoid assembly. The switch provide input information to the Transmission Control Module (TCM). The switch will inform to the TCM is pressure exist in a specified hydraulic circuit. the TCM uses this information to verified that the solenoids are working or not.
