P1316 Code 7.3 Powerstroke

Using the Ford 7.3L, users are notified of any issues with their engine through Diagnostic Trouble Codes (DTCs). One such DTC is P1316 code 7.3 Powerstroke, indicating a problem with the IDM. If this code is encountered and the user is unsure of its meaning, an article has been written to discuss associated symptoms, causes, and solutions.

What Does the P1316 Code Mean on 7.3L Powerstroke?

The DTC P1316 is associated with the Ford 7.3L Powerstroke engine, indicating that Injector Driver Module (IDM) Codes have been detected by the PCM (Powertrain Control Module). OBD-II scanners cannot read IDM codes, so an error code of P1316 informs users that a Bi-Directional Scan Tool must be used to read any resulting codes from the IDM.

This code may lead to three issues, regardless of whether a Bi-Directional Scan Tool is employed.

  • UVCH Connector Problem
  • Out Of 8 Injectors, four or All Of Them Are Sticking Together (Rare Case)
  • Faulty IDM (Rare Case)

Understanding the symptoms associated with a Diagnostic Trouble Code (DTC) of P1316 is important to diagnose and address the issue.

This error code is a frequent occurrence in 7.3L engines, indicating there may be an underlying design flaw that affects the UVCH connectors. It is important to take steps toward rectifying this issue as soon as possible to preserve optimal performance.

Various factors, including incorrect fuel injector timing, faulty wiring or connections, and an issue with the powertrain control module, can cause the error code P1316.

  • Loose or Disconnected UVCH Connector
  • Bad UVC Harness
  • Faulty Injector Driver Module and wirings (Rare Scenario)

The only way to resolve this error code is by addressing the above causes.

How Serious Is Code P1316 On 7.3L Powerstroke

When a car experiences difficulty starting and other technical issues, it is likely that the DTC P1316 trouble code has been activated. This error code can have serious implications for an engine, so it should be addressed immediately to avoid further damage. While the issue can often be resolved with basic DIY repairs, professional help may still be required if necessary.

How To Solve P1316 Error Code On 7.3L Powerstroke?

Accurate diagnosis requires further investigation to locate the source of an issue causing the error code P1316.

Detailed troubleshooting is necessary to resolve this error code effectively.

Let’s get started with identifying the injector problem first:

Identify Injectors Problem & Error Codes First

The extraction of error codes will assist in identifying the underlying issues with the engine. These problems can then be addressed and resolved individually to remove the code.

Tools You’ll Need:

Investing in an AutoEnginuity (AE) Scan Tool is recommended to perform a KOEO (Key On Engine Off) Self-Test, also known as the Buzz Test. At around $500, this tool will effectively assist with troubleshooting car issues.

KOEO Self-Test Of The 7.3L Powerstroke

The AE ScanTool can be used to run a KOEO self-test. The injectors should be listened for, with four on the driver’s and four on the passenger sides. Each injector has its own numbered description when assessing performance; number one is located at the front of the engine, and two through eight are in descending order from right to left.

  • Driver Side (Right Bank): 2nd, 4th, 6th & 8th Injectors
  • Passenger Side (Left Bank): 1st, 3rd, 5th & 7th Injectors

Determining which side of the exhaust manifold is causing the issue can be done by following simple steps.

Step 1: Conduct the test & you’ll hear all injectors are buzzing at once.
Step 2: Now, you’ll hear them buzzing one by one. Count them like this: 1, 2, 3…. to identify the injectors.
Step 3: Take notes on which injectors are having issues(Passenger or Driver side) as it helps you determine & fix the problem.

Note: The IDM can provide DTCs to the KOEO Self-Test/Buzz Test, so it is important to act accordingly. Alternative methods may not be able to produce additional error codes for further analysis of the issue.

KOEO Self-Test/Buzz-Test Alternative

Utilizing the AE Scan Tool can be costly; thus, other options should be considered. One alternative is to use a Harbor Freight item that ranges between $40 and $50 or a Temperature Gun, which many people already possess.

Temperature Gun For Identify Injectors Problem

Identifying which exhaust manifold is having issues can be accomplished by following the appropriate steps.

Step 1: Let the engine run for 4 to 5 minutes.
Step 2: Hold the temperature pointing to each exhaust manifold.
Step 3: The exhaust manifold with a lesser temperature has power issues.

This article provides instructions on how to fix injector problems once the corrupted part has been identified.

1. Check UVCH Connector: Reconnect Or Replace

It is possible to determine which side of the Valve Cover Harness (UVCH) connector is faulty or having issues through tests conducted. To do this, the valve cover must be removed, and the turbo side should be loosened to avoid spending money on new o-rings. Upon examining the UVCH connectors, they may be either loose or disconnected and need to be reconnected or tightened accordingly. In cases where these connectors are in poor condition, they can also be replaced with shims to prevent further loose connection problems.

2. Check & Replace IDM (Rare Case)

When there have been attempts to resolve the UVCH connectors issue without success, it may be time to examine the IDM (Injector Driver Module). Testing an engine’s 7.3 IDM can help determine whether it is defective. If found damaged, replacing it at an automotive shop would be appropriate.

Note: The troubleshooting methods for IDM not splitting severe DTCs during the Buzz test generally include these steps. In cases where two or more codes are given, seeking professional assistance is recommended.

How Much Does It Cost To Solve The Error Code P1316

Scanning tools and scanners can be a costly purchase. However, price lists are available to aid in the decision-making process. Considering the tool’s purpose and features is important when looking at these price lists.

  • OBD-II Scanner: $150+
  • Bi-Directional ScanTool: $450+
  • Harbor Freight: $40+

They may have to purchase UVCH connectors for around $30.

Professional assistance could be procured, for which one may need to pay between $75 and $150 per hour.

Common Mistakes While Solving The P1316 Code

It has been observed that many individuals frequently make mistakes while attempting to resolve the error code P1316.

  • Reading the injector’s buzz sounds wrong.
  • Not using a Bi-Directional Scan Tool if needed.

Additional Comments To Consider Regarding The P1316 Code

When dealing with a P1316 code 7.3 Powerstroke, replacing the UVCH connectors may be enough to resolve the issue. However, using a Bi-Directional Scan Tool is recommended to check for any other IDM codes and ascertain the true cause of engine misfiring. If purchasing such a tool is not an option, taking the truck to an auto shop can help diagnose and address the problem.

Last Words

This article has provided enough information to understand the DTC P1316 better. With this knowledge, one can potentially identify and solve the code without the expense of hiring professionals. However, should attempts at resolving the issue fail, professional assistance may be necessary and will cost more in the long run but could result in substantial savings.
