P0788 - OBD Trouble Code

<<See All OBD Codes

The trouble code P0788 can be elucidated as Shift Timing Solenoid A High. The major function of the solenoid is to control the automatic transmission fluid flow to help in shifting of the transmission. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

Are you tensed because the P0788 fault code is flashing? We have got everything which you need and at equitable prices. You must visit us and we promise that you will never regret your decision. It is the engine control module which would illuminate the malfunction indicator lamp with the P0788 fault code. The other related codes are P0785, P0786, P0787, and P0789. This trouble code would start appearing when the ECM would monitor one or more issues within the shift timing solenoid.

What causes this problem with the Shift Timing Solenoid A High?

• There can be inoperative wiring harness
• TCM might be flawed
• Defects in the shift timing solenoid
• The automatic transmission fluid might not function properly
• Little ATF
• Some issues related to the ECM
• Imperfect Pin/connector

Here are some steps which you should follow in order to diagnose this fault code:

First of all, you would need a diagnostic scanner, a digital volt/ohmmeter, and a reliable vehicle information source to diagnose a code P0788. Check for technical service bulletins which pertain to the vehicle, symptoms, and codes. Make sure to check the automatic transmission fluid. You must change your fluid if it is grimy, smells burnt, overfilled and unusual colour. If you've owned your vehicle for 30,000 to 60,000 miles and you do not remember when was the last time you changed your fluid or have any records of it, not only may this be your issue, but you should follow your maintenance schedule to avoid this situation. Former fluid is mucky fluid, grimy fluid can cause blockages and blockages can be a big reason why this fault code is appearing so you must change your fluid! The manufacturers recommended steps should be followed properly when you are inspecting ATF. This basic step can differ a meaningful amount between the models as well as makes. The fluid is in nice condition, code is still present and symptoms exist? It all depends upon your specific model; the shift solenoid may be accessible externally. Now if you find out that this is the case, then you should check the solenoid and its harness/connectors to find out the signs of defect.

All the issues should be repaired or replaced as per the need. It would be helpful if you will have a peak for any leaks as well! If your shift solenoid is internal, then you should attempt to access it, work around it for now. Exhaust other avenues, internal transmission diagnosing and repairing should be left to a certified technician. The TCM and harness' involved in this circuit may be subject to rasping road conditions so make sure everything is complete in all aspects. After that the shift timing solenoid should be inspected. You may be able to test the solenoid itself multiple ways. One test may include a resistance test where you use a multimeter to measure the resistance between the pins in the solenoid to verify to a degree its electrical integrity. Then the other would include manually applying voltage to the solenoid to verify its mechanical operation. You should specify either one in your manufacturers service manual/technical literature. The circuit from the TCM should be tested properly. Then check the functionality of the sensor and its circuit by performing the same tests as above but from the pins at the TCM and/or ECM. This trick would be very helpful in verifying the integrity of the solenoid as well as electrical integrity.

Common Mistakes When Diagnosing The P0788 Code

It’s possible to diagnose a P0788 code as defective shift solenoid issue, when the problem is an issue related to the shift solenoid circuit. You must inspect and test all electrical wiring and circuitry carefully before you start performing any other repairs.
