2008 Honda CR‑V Throttle Position Sensors (TPS): What They Do and How They’re Serviced

Technical sources confirm the 2008 Honda CR‑V is equipped with throttle position sensors. Honda’s 2007–2011 CR‑V Service Manual (Electronic Throttle Control System, “TP Sensor A/B”) specifies dual, built‑in throttle plate sensors within the electronic throttle body, and common OBD‑II diagnostics list TPS‑related DTCs (P0122/P0123 for TP Sensor A, P0222/P0223 for TP Sensor B, and P2135 correlation). OEM parts catalogues also show the TPS is integrated into the throttle body assembly rather than being a separate bolt‑on switch. So, the TPS is very much used—just not as a stand‑alone, serviceable unit.

On a 2008 CR‑V, the TPS forms part of the drive‑by‑wire setup. Two sensors inside the throttle body track the throttle plate angle, while an accelerator pedal position sensor tells the ECU what the driver wants. The ECU cross‑checks these signals for safety and smooth response. When the TPS goes out of range or the signals don’t agree, the ECU can trigger limp mode, cut power, and light the MIL.

Typical symptoms owners may notice include:

• Hesitation, hunting idle, or stalling under the bonnet
• Reduced power or cruise control dropping out
• MIL on with codes like P0122, P0222, or P2135

Because the TPS is built into the throttle body, replacement normally means fitting a complete throttle body assembly. That’s the factory‑approved fix in Honda literature and in systems like Alldata/Mitchell. A technician will remove the intake duct, unplug the connector, swap the unit with a new gasket, torque the fasteners to spec, and perform an idle/throttle angle relearn. On these Hondas, a proper relearn (scan tool or service‑manual procedure) is crucial so the ECU knows the exact closed and open positions. Skipping this step can cause rough idle or high idle.

As part of routine servicing, careful throttle body cleaning helps. Use throttle‑safe cleaner sparingly, don’t force the plate by hand, and avoid flooding the electronics. Inspect the connector and loom for corrosion or rubbed‑through insulation, as wiring faults can mimic a bad TPS. If codes return after cleaning and checks, replacement of the throttle body is the reliable remedy. Quality parts and a relearn save heaps of grief, and most shops can turn this around in a couple of hours.

Popular questions

Does a 2008 CR‑V have a separate, replaceable TPS?
It doesn’t. The throttle position sensors are integrated into the electronic throttle body assembly. If the TPS fails or sets correlation codes, the recommended repair is replacing the entire throttle body and carrying out the relearn.

Is a relearn needed after cleaning or replacing the throttle body?
Yes. After cleaning or replacement, the ECU needs to relearn the throttle’s minimum and maximum positions. Without this, idle quality and throttle response can be off. A scan tool procedure or Honda’s manual idle learn routine does the trick.

What warning lights or codes point to TPS issues on a 2008 CR‑V?
Common TPS‑related fault codes include P0122/P0123 (Sensor A), P0222/P0223 (Sensor B), and P2135 (A/B correlation). The MIL will light, and the vehicle may enter limp mode with reduced power to protect the drivetrain.
