If you’re experiencing “Edge Cs Insight No Obdii Readout” issues, installing an Exhaust Gas Temperature (EGT) probe might be a solution. While this doesn’t directly address OBDII communication problems, monitoring EGT is crucial for engine health and performance, especially when modifications are present. This guide provides a step-by-step walkthrough of installing an EGT probe on a truck, specifically focusing on the mechanical aspects of the process.
Drilling and Tapping the Exhaust Manifold
The installation process begins with preparing the exhaust manifold for the EGT probe. This requires drilling and tapping a hole to accommodate the probe fitting. The following tools and materials were used:
- Drill Bits: 1/8″, 3/16″, 17/64″, 19/64″, and 21/64″ (incremental sizes for gradual drilling)
- Tap: 1/8″-27 NPT (to create threads for the fitting)
- Tap Handle
- Drill
- Sharpie (for marking)
- 9/16″ Wrench
- Safety Glasses (essential for eye protection)
- Flashlight
The chosen location for the probe was on the rear of the driver’s side exhaust manifold, on the bottom.
Drilling was done incrementally, starting with the smallest bit (1/8″) and gradually increasing to the final size (21/64″). This gradual approach minimizes the risk of damaging the manifold and ensures a clean hole. Slow and steady drilling, especially when the bit is about to break through, is crucial.
After drilling, the hole was tapped using the 1/8″-27 NPT tap to create the necessary threads for the EGT probe fitting.
Installing the EGT Probe and Wiring
With the hole prepared, the fitting was screwed in, followed by the probe itself. The probe was then secured by tightening the nut.
The probe cable, with the EAS connector, was routed to the firewall, behind the master cylinder. This is where the connection was made between the probe cable and the EAS cable (which connects to the Edge CTS Insight monitor).
The EAS cable was then run through the firewall grommet, up through the dash, and to the A-pillar where the Edge CTS Insight was mounted. Minor trimming of the pillar mount was necessary to accommodate the EAS cable.
This installation allows for accurate EGT monitoring, a valuable tool for maintaining engine health and performance. While it doesn’t directly fix “Edge CS Insight no OBDII readout” errors, having insight into EGT can help diagnose potential issues that might contribute to communication problems with the OBDII system.
